Error 0x80070079: The semaphore timeout period has expired
Whenever I try to copy large files over a wireless network (Laptop > Desktop) I get the following error:-
Error 0x80070079: The semaphore timeout period has expired
I've done a search on Google and have found that a number of other users are having the same problem, but no-one seems to have a fix for it.
Can anyone help?
(I'm running Vista Ultimate on both my Laptop & Desktop)

Hello Ady,
Thanks for your post!
This issue may be a little complex and require some steps to troubleshoot:
1. Update the driver of wireless network adapters in both of your computers.
2. Temporarily disable all the firewalls and anti-virus applications, then check the issue again.
3. To exclude the factors from other services and applications, do a clean boot to check the issue and perform Step 4.

- Hi,
I'm getting the same error but in a different -- seemingly less complicated -- context. I am trying to backup my main drive to an external eSATA drive. Every file copied without incident except for one movie, a 143 meg WMV. Here are some facts about my situation
1) the folder contains 90 videos (all homemade so copy protection isn't the issue)
2) the video sizes range from 1.2 gigs to 34 megs
3) copying was smooth and fast, except for that one file
4) I thought that it might be the eSATA drive but I got the same error when copying to the same HD, same folder or different folder. Clearly wirelessness, network issues and other connections (USB, firewire, etc) aren't the problem.
5) I'm running Vista Home Premium with all the latest updates on an HP Media Center computer running AMD x2 5200+ with 4 gigs RAM
6) I tried repeatedly, even after multiple reboots and still got the error for this one file
7) I tried ZIPping it and got the same error
8) Strangely, it seems to play just fine in Windows Media Player
There are hints of viral activity and I've had 3 Blue Screen crashes today (which is why I'm backing everything up before reformatting my entire drive).
My last hope is to upload it to a site like Yousendit and then download it. Even if you don't know what's wrong, can you offer any tricks to get around the error and backup the file?
Please help. Thanks for any advice in advance,
Sam Sam,
Like you, I got the message while attempting to copy files within one system.
1. The files were large video files (100MB to 600MB);
2. Some smaller files of the same type copied successfully, but not all;
3. The hardware involved is an external Plextor 810UF (USB) drive to my "D" (work) drive;
4. Sometimes the timeout would occur while the system said it was calculating the time of the procedure. At other times it would start the process and then hangup. (A couple of times I got a message which said the process would take 45000+ days and 12 hours. I really don't feel I should have to wait 125 years for things to happen. <GG>)
I am able to work around the problem by connecting the Plextor to an XP PC and then transferring the files to my Vista PC (same drive and directory that I tried before) via a cabled Linksys router. So far that works flawlessly. Therefore I'm sure the problem isn't in the network.
I hope that a solution is forthcoming because the work around is a bother.

- I haven't found an answer to this problem anywhere, yet it seems to be quite common.
I'm using HP MediaSmart Server to do automatic backups. Everything was working ok until one day I got the following error:
An unexpected exception ocurred on the computer. COMException. The semaphore timeout period has expired (Exception from HRESULT: 0X80070079) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRIntern at (Int32errorcode IntRtrerrorInfo).
I checked the the Crashdump and it referred to Pinnacle11 (video editing application), and cooincidentally, the problem only started after I had been editing a couple of video files.
Has anyone yet found a fix to this problem?
Steve Well I don't have the answer but perhaps I can simplify the problem even more for MS. I am running Windows Home Server and everytime WHS tries to go do a daily backup of my workstation, the backup fails with these two error messages -

Many of my larger video files are .mkv format which may also be related somehow. If anybody finds the solution before me, please let me know. Thanks.

Well this did'nt work for me.
Any other solution?
Using XP Prof. Service Pack 3 beta.Hi All,
Similar problem with backing up one laptop running Vista Ultimate x86 on to a WHS over a 1 gigabit LAN wired connection (DLINK G604T + Netgear switch); the laptop contains some large video files (DivX, .iso) 800mb - 2 gb and the backup proceeds until about 35% with the same 267 error previously described in the event log on the WHS, and a report on the client laptop that there was a problem accessing a specific file on the WHS server.
I have no problems backing up the desktop running XP pro that has also has some smaller home movie files on it in their original state, on two WD raptors RAID 0 on a silimage controller.
This is really ironic in a truly MS sense, that a server specifically designed to backup your media so you can never lose them to a drive crash or viral event or whatever hole nobody noticed, won't back up your 'precious memories' on a vista machine.
Since my desktop doesn't exhibit the problem, I will be keeping all my video files on that machine having removed them from my vista laptop and see if the problem resolves. The only other suggestion I can make to vista users until a fix is found is to eihter burn all your larger video files to DVD or a high capacity removable usb drive, or revert a machine to XP if you can and use that to store video media files.
If you happen to get tired of being a slave to the machine, like I do, just remember you can always turn it off and go play someplace else... and if you are considering buying WHS and only have vista 'clients' hold off for now. I will report back once my video files have been swapped over to the xp machine and see if I can get a decent usable backup of this laptop on the WHS. There also seem to be references to issues with my shadow copy drives in my WHS event log as well. Apparently they can't grow. A truly underwhelming experience.
Hello Again,
Yep my 'workaround' worked for me. After removing all of my large media files including an image that was over 7gb (a game beta), by burning most of them to disk and deleting them from the hard drive (+ emptying recycle bin) afterwards, I finally managed to back up this vista laptop.
Given that I didn't change any other aspect of my config, and backed up the laptop the way I usually do with Acronis True Image beforehand, one can only summise that WHS has issues backing up large video files, or video files of certain file formats.
I guess this method atleast gets around the problem and in no meaningful way identifies the absolutes and specifics of either the actual problem or how it can be resolved per se, but it does crudely isolate the issue and privide a stop-gap until someone way mucho intelligent than I with the time to spare can get down to tin tacks and figure it out thoroughly! That's about the longest sentence I have ever written in a post.
If this helps someone avoid losing a file, like me for instance, I guess it was worth the cognitive effort. Hope it provides some short-term helps to others. Good luck.
I also had this problem when i tried to copy over the cable or wireless connection from laptop to desktop. the workaround that I tried is to give the copy command from the desktop to copy from laptop to desktop.Same problem here: Error 0x80070079: The semaphore timeout period has expired
Error occurs multiple times when transferring files of 10MB and smaller (no large files at all) on a shared external USB harddisk connected to PC1 to another folder on the same external USB harddisk from a laptop.
Copy command is issued from PC2.
In my opinion this is NOT caused by a network issue or should not be possible to be caused by the network.
PC1 (OEM Desktop) - Wired Gbit LAN:
MS Windows Vista Home Premium SP1
Shared external HD with full rights to everyone
PC2 (Lenovo Laptop) - Wired Gbit LAN:
MS Windows Vista Business
Switch:
3Com OfficeConnect with 8 Gigabit ports
External USB HD:
USB Western Digital Elements (400GB)
( I could not find any entries in the eventviewer about this error. )
- This is very interesting. The current trend is laptops and video files. I am also having this problem with a Dell D610 latitude running XP Pro SP2. I am capturing video from my Canon GL1 via 1394a PCMCIA card into Sony Vegas 8 Pro. All I get is the error code 0x80070079. It will randomly occur during the capture process into uncompressed AVI's. It is rather frustrating because I was considering that my firewire card was bad, but reading other peoples' problems leads me to think otherwise. Is it possible that it is a problem with a hard drive controller common to laptop motherboards? My controller is an Intel 82801FBM UATA controller. Just something to think about. It would be nice to solve this issue. By the way, this is really the only issue I have with this machine, everything else works great and memory checks out fine with MemTest.
- It's not related to videofiles, it's related to large files. I have a Dell Inspiron 1720, Vista Home, a HP MVP 5020, and a Linksys 54G router. With wireless connection, any files larger than a few mb's causes complete disconnection after a few seconds, IP is lost and has to be reaccuired. With wired connection any size file can be transferred. On my Mac, I have never seen this problem. Don't have any solution but, are very annoyed with this.
BR.
T. - I have recently received same message on my laptop running XP.
Trying to upload photos using a media card reader. The SD card is a 1GB card.
I have both a laptop and desktop running XP(updated), but when the media reader is plugged in the USB with the SD card installed, the desktop locks up. I don't remember having this issue using a smaller sized SD card, say 16MB.
My wife has a laptop running Vista, I have had no problems with that particular machine. - Actually it is neither video nor large files that is the only culprit.
I have an HP Pavillion dv9413cl Notebook running Windows Vista Ultimate. It has two hard drives. I just added the second hard drive to the machine and installed a fresh clean install of Vista on the newly installed hard drive as it is now my primary drive. The old hard drive has all the old data on it.
I am in the process of cleaning up the drive and consolidating needed data. In the process of deleting a few files I received this error, not only through Windows Explorer but through a command prompt as well. Here is my output of the command prompt window.

3 File(s) 911,932 bytes
As you can see we are looking at sound files of a few hundred K. So not video or large files.
This also rules out any intra drive transfers, network contention, or the like as I am just trying to delete the files not transfer them over some medium. - This is a weird one. I'm also thinking that large video files are just one symptom of the problem, because I am getting it whenever I try to access a shared folder on another PC via Windows Explorer.
Everything had been working fine when both machines were running Vista Ultimate, and I never encountered this error. But since upgrading my laptop to the Windows 7 beta, I have never been able to connect to a share on another machine without seeing this.
I'm pulling my hair out trying to finx a solution - sure hope someone comes up with something before I go bald! :-)
Rob - I've got the same msg trying to use Vista Ultimate Backup. I have two internal sata drives and I'm attempting to back up from C to D when it halts with this msg. I then tried to copy my docs folder using the desktop. Same problem. It's SP1 with all drivers current.
I used to tell everyone how good Vista is but this is really concerning me.
- This error is usually the result of a DHCP renewal. Switch to using static IP addresses and see if that helps. You are most likely experiencing a DHCP address renewal during your file copy operations. If you need to use DHCP, try increasing the lease period, and if you don't control the lease period, find out what that period is and do an ipconfig /release and then an ipconfig /renew in a command prompt to cause the lease not to renew itself during your backup window.
I ran into this problem while attempting to do a backup of my C drive. Running a check disk on the drive cleared up the problem.
- i found a solution for people trying to move video on to sd cards without coming up with these errors.
1. download and install winrar.
2.select your file and click on "add to archive".
3.now select "compression method" and select "good".
4.now you need to split your file by selecting "split your volume in to bytes" and select zip100:98078kb
this will now split your file in to 98mb size pieces, i did this with a 696mb and got 6 seperate rar files.
when it has finished, move them one by one on to your card and when you have done this select them all and click "extract here"
this will now unzip and piece your vid back together.
i hop ppl out there find this helpfull in some way ;)- Proposed As Answer by[Chronic]Chesh Friday, March 06, 2009 9:43 PM
- This problem seems to be about DHCP. I get it when my NIC suddenly stops holding an IP lease even if there is no traffic. I have the latest NIC driver so none of MS' suggestions help. It has nothing to do with any router, ISP as I have tried many combinations. The OS seems fine. I've tried AutoNegotiation and 10MBFD. Same problem. This has wasted about two weeks of my life. Any help would be appreciated. My NIC has many undocumented settings but I have them all on the default and none seem to have anything to do with timeouts. Power management is 'always on' for the NIC and OS. It is a NVIDIA 10/100/1000 NIC.

- I did not mean to click propose as answer. I was reading the button as Propose AN Answer, my bad. I have had a lot of problems on my home network transfering lots of data between 2 machines. The main problem child is my Vista machine. I think the NIC in it has some compatibility issues but what I did for a workaround was install sync toy. It is a great little utility for syncing folders between machines. It has built in retries so even if your transfer bags it, you will not have so start at the beginning. You will not have to click no or yes to all on overwrite if you have to start again on a large multi file transfer. It will scan source and destination and only copy whatever files still need copied. Give it a shot. I love it.

Have fun and let us know if this gets around the timeout errors. What's the worst that could happen? - Well, since about half the people on this aren't transferring over a network, I would say that DHCP isn't the problem, at least in those cases. I for one am getting this error transferring files from a 256MB USB thumb drive and from a 120GB external USB HDD to my IBM T41p Laptop running Windows XP Pro SP3. The smallest file I have had this trouble with is a 29.8MB data file. I am also getting the error while simply trying to access folders on these drives that contain large amounts of data in them. I suspected it was a problem with my USB controller as I recently started getting other USB related errors about my USB 2.0 services not working with the device even though all of my drivers are updated and the host controllers indicate they are USB 2.0 capable. First, I tried updating my BIOS. I had no change after doing this. Naxt, I installed a USB 2.0 capable PCMCIA card. I am no longer getting the USB errors this way but I am still getting the "semaphore timeout period" error. So I don't think it is related to the USB ports. Oh, and just for te record, this is a pretty fresh install of the O/S so everything is still pretty clean.I would say that this error appears to be a generic error that appears whenever something times out during data transfer, regardless of the medium or protocol, on machines running MS Windows XP and Vista O/S. What causes it in each case could be different, thus the difficulty in troubleshooting. Consequently, I doubt that one fix will solve everyones problem, but perhaps through this forum we can dial it down to all of the most common causes and fixes. I have tried all the ones here for my case with no luck, and I can see that others have had the same trouble.If anyone has any ideas about my particular situation please advise. I will try anything at this point.
- Although I agree this error is not exclusive to networking, this thread was started (almost two years ago now) by someone with a network issue and is logged under networking. (" Windows Client TechCenter > Windows Vista IT Pro Forums > Windows Vista Networking ")
I've seen this error whilst trying to access a suspected faulty IDE drive attached via a USB interface. (Size and type of files irrelevant) It seems to me if you want to start to understand semaphore timeouts you can just leave out the word "semaphore" ... - Well to those that bother to keep track of these issues...I for one am still having the same drama. For extra interest, it does not happen across a wired LAN!
Will (or perhaps they have) MS fix this?
Vista on HP Pavilion dv5 AND static IP address. Server is Ubuntu 8.04. Vista is the only OS that has this drama.
Rrrrrrrrrrrrrrr - "Me too" I've been getting this with my Windows Home Server for the past 6 days. Checked the Event Log, rebooted the server, searched the web. Still fighting it. Posted something on the Home Server Forum earlier, will see if that leads to anything.
- The moderator on the WHS forum suggested this, and it worked for me:
"Try running chkdsk /r on all the drives of the client having the problem."
Good luck to all others.

Hi guys,Whenever I try to copy large files over a wireless network (Laptop > Desktop) I get the following error:-
Error 0x80070079: The semaphore timeout period has expired
I've done a search on Google and have found that a number of other users are having the same problem, but no-one seems to have a fix for it.
Can anyone help?
(I'm running Vista Ultimate on both my Laptop & Desktop)
I experienced this trouble for about a week, trawling forums and googling to the point where i had just about given up.
Microsoft are no help at all, they know this problem exists yet ignore all requests of help to find a solution.
Anyway, I managed to resolve this issue by installing a patch called 'Vista TCP/IP & UAC AutoPatch'.
More info here http://www.netfresco.com/tech/network-copy-failure/ or directly download the patch from here
http://www.softpedia.com/get/Tweak/Network-Tweak/TCP-IP-Limit-AutoPatch.shtml
This solution worked for me and i have no hesitation in recommending it.
BTW this patch is vista 32 and 64 related, so if you are an XP user then unfortunately this may not be of any help.
Good luck guys.
Brassnex- I too received this error last night. I was backing up a brand new installation of Ultimate, do an existing 500GB WD sata drive. My dilema, is that it has appeared to corrupt my hard disk. After I received this error, I rebooted and the drive is no longer available. I supposed it is possible that I have a hardware issue with my controller, but...
- Me Too. I bought a new 500gb imation apollo hard drive. was worried about losing my data since moving country and leaving old backup at home. running my first backup. go out and come back home. first weird thing that happened is all of my torrents I was downloading had disappeared, then computer starts freezing, receive 'the login process has failed to create the security options dialogue box". I wonder if it has to do with installing the new backup drive (USB). Very frustrating. Now trying to back up so that I can install everything from scratch, but getting the timeout error!! grrrr
- Hello,
here is solution for problems with sdhc memory sticks (or beter problems with Ricoh card reader).

Thanks! Hard an OS that is fit for purpose.- Hello
I have lately the same problem. I changed my NAS from Thecus N5200PRO to N7700Pro. Copying to this new NAS causes this error. As soon as round about 40MB/s are copied the wireless connection aborts and never came back. I have to unplug the router and reboot it to get it working again.
Info:
Windows Vista Home Premium 32 bit (Intel WiFi 5100 AGN - latest driver v13)
Router -> LinkSys WRT54G (Wireless G - 54 MBit Connection).
Observation:
Even due to the fact that the router not supports 802.11n some moments before the wireless network vanishes the connection speed is shown as 300 Mbits connection. - Microsoft is incredulous, ignoring this long-standing "semaphore timeout" issue.
I OFTEN get this "semaphore timeout" on my VISTA BUSINESS system when even trying to do a "dir" command on my Buffalo NAS (network attached storage) via the mapped drive.
I believe this is simply a timeout regarding the response from the NAS (or any drive share).
I believe the timeout is seemingly random, thus why some people experience it on even small files, but with large file you increase the liklihood of a timeout due to more opportunities for it to happen given the longer period of time.
Note: I also sometimes get error, "The specified network name is no longer available" when even doing a "dir" command.
It is not DHCP as suggested earlier, because I have a static IP.
I am wireless, and wireless often gets brief interruptions in data streams, so my guess is that it is that. You can such interruptions such as when you watched some streamed videos from the Internet and they simply stop altogether - very frustrating!
MY FIX:
As a test, I connected to my network via ETHERNET (LAN) CABLE, rather than using wireless, and over the past hour of doing periodic copies, I have not had any timeouts.
This doesn't explain the problem those of you are having with USB and SD cards... but, perhaps whatever device you're using is so slow, say, an SD class 2 card, that timeouts result, so perhaps and SD class 6 card wouldn't give such an error. Similar for the USB product, perhaps the attached item only communicates at on USB1 speeds and not USB2 speed?
So, Microsoft needs to do something about the timeout or the handling of sparatic disconnect states to allow a resume upon reconnection????
I also like the idea of doing the CHKDSK /R that was suggested by someone else above - it cannot hurt, and who of us do this even once a year!? It should be done as regular maintenance. Do it on both your PC and on your NAS or USB or SD drives. - I have the same problem with both network and external HDD via USB.
I hope someone will come up with a solution. - Don't as me why but the follwing command "work-around-ed" the problem within my network (just execute in command shell):
netsh int tcp set global autotuning=disabled
But MS should really soon come up with a proper solution. This is dam annoying! - Well if it makes any difference, I upgraded from Vista Ultimate to Windows 7 Professional and I am still having the same problem. I have been working with MS for over a month now with no resolution yet. My backups fail with my Outlook file - which is under 1Gb and now the Windows Media database is failing as well. I have both wireless & a lan cable plugged into my laptop and the external HD is brand new Seagate 1.5TB. It's amazing that this has been going on for so long with no resolution from MS.
- Rosedio,
Often you cannot backup files that are open, never can backup an open .pst files (outlook files for home use).
Make certain your outlook.exe is closed -- I would suggest ctrl-alt-del and make sure no outlook.exe is running (I've had several times it stays running even if I use file>exit from the menu).
Similarly, database files will not backup if the database engine is running.
In your case of Windows Media database, make sure to first stop service windows media. Click START > RUN> ..type in.. services.msc > find "windows media" item(s) and stop it (personally, I have them disabled )..
also stop any SQL service(s) you may see on your PC for other databases...
Really, "backup" is best run in safe mode which has a minimal # of running services and running programs that are locking up files.... That's why you pay the big bucks for backup software like Backup Excec because they can backup database and locked files off of MS VSS versions...
In most "normal" people's cases, however, we don't really have many locked files to worry about, so we use the freebie and manually shut off processes before backup.
John - Same problem here with Windows 7 Professional when copying one 300 MB file to a WebDAV storage. Seems to be an old MS bu^W feature.
- I finally fixed the problem. I had the same error over and over again.
In my case it was the security of my router. It was set to WPA-PSK. I disabled it and now it runs perfect...

I had almost tried everything until I did the same, changer my router from WPA-PSK to WEP. Transferred my large file without issue in seconds.
Thanks dreads76!
