Backup failed "... the connected party did not properly respond after a period of time..." (0x8007274C) RRS feed

  • Question

  • I recently added a couple of newly built 2008R2 Standard boxes to DPM.  One is a new DC, the other will be, but is just serving files and printers at the moment.

    I'm trying to back up one file share on each of these servers.  I've pushed the agent from DPM and added the servers to the protection group.  The agent status shows ok on the management tab.  The backup is failing. These servers show alert "Replica is Inconsistent".  The detailed error is:

     

     

     

    Affected area:	C:\
    
    Occurred since:	12/20/2011 6:08:10 PM
    
    Description:	The replica of Volume C:\ on DCMO.DOMAIN.com is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent. 
    
    
    
    For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106)
    
    	DPM failed to communicate with DCMO.DOMAIN.com because the computer is unreachable. (ID 41 Details: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond (0x8007274C))
    
    	More information
    
    Recommended action:	1) Make sure that DCMO.DOMAIN.com is online and remotely accessible from the DPM server.
    
    2) If a firewall is enabled on CHC-DCMO.davchc.com, make sure that it is not blocking requests from the DPM server.
    
    3) If you are using backup LAN, make sure that the backup LAN settings are valid.
    
    	Synchronize with consistency check.
    
    	Run a synchronization job with consistency check...
    
    Resolution:	To dismiss the alert, click below
    
    	Inactivate alert
    
    

    The windows firewall is turned off by GPO.  I am having a couple of other alerts on other servers, but they are completely different errors, and I don't believe they are related.  
    What can I do to get these backups working correctly?

  • If you run a Consistency Check (CC) as recommended which error do you get (if CC fails, post the error by looking into Monitoring/Jobs and highlighting the failed CC job)?

  • Hi Gai-jin,

    How long does it take for the CC to fail?

    What I would do is to disable TCP Chimney and RSS on both DPM server and the one you are getting this error from.

    To disable TCP Chimney: netsh int tcp set global chimney=disabled

    To Disasble RSS: netsh int tcp set global rss=disabled

    Ref: http://support.microsoft.com/kb/951037

    Besides this you might want to disable TCP offload from the Adapter drive settings like this one below

    Note: Be aware that when you click Ok after disabling these options you might lose network connectivity for a short brief period of time.  

    I also recommend you to reboot both servers after this changes are in effect.

    Let us know if this resolved the problem.

  • It fails after about 10 minutes.  I'll try making the changes you suggest and see if they help, but I'm probably not going to get to them tonight.  With the holiday weekend, it may be Tuesday before I get back to it.  

     

    I've got to think it's something I did wrong when setting these servers up, since it's 2 newly rebuilt servers -- 1 is a brand new hp rack mount server, and 1 is re purposing an old ibm blade, but both are fresh installs of the OS.   I just don't know what I might have done any different than I have in the past.

  • Configuration should be ok. We've seem communication issues between DPM and protected server due to RSS/Chimney. Hopefully this will resolve the issue for you....

  • Okay, I have made those changes, rebooted the server, and am still not able to get a successful backup.  Looks like I'm getting the same error on the CC job:

    DPM failed to communicate with CHC-DCMO.davchc.com because the computer is unreachable. (ID 41 Details: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond (0x8007274C))

    Any other suggestions?

    Tuesday, December 27, 2011 11:15 PM
  • Thanks for the update.

    From that machine, which datasource you are trying to back (volume, share, SQL, etc)?

  • Is this the only server you are having problem with (host has failed to respond (0x8007274C))?

    Is this server multi-homed?

  • hi Gai,

     

    Is this is a trusted domain server that you are trying to protect?

    Is there any firewall between? (disable the firewall just to test)

    Check if the local account on the DPM is set to password never expired. If you are protecting a DC search for DPM in the AD and check the account option for the Protected server members of trusted machines. The password should also be setup to never expire.

     

    Check the Event logs for the protected servers.

  • I'm having this issue with 2 servers, both recently rebuilt with clean installs of 2008R2 w/SP1.  The hardware is not the same, one is a 2 year old IBM Blade, the other is a 3 month old HP rack mount server.  If one of these hadn't already been promoted to a DC, I would just wipe them both and reinstall, in case I made some kind of mistake in setting these up, installing agents, etc, but at this point I'd prefer to avoid that if at all possible.

     

    Both servers have just 1 nic connected, with a single static IPV4 address.  The HP server does also have the ILO port connected, with another IPV4 address from the same subnet, but windows shouldn't see that address anywhere.  Both servers are a part of the same domain as the DPM server, and there is not a firewall between the dpm server and the servers to be backed up.  

     

    Laith_IT - I'm not sure what you want me to check in AD.  A search for DPm finds 4 groups that begin with dpmra, and 2 end with the name of one of the servers I'm having issues with. The other 2 end with the name of a server that has been backing up fine for several months. 

    Event log on the protected server -- I see a VSS error in the application log, but it's not happening every time there was a failed job, so i'm not sure if it's related:

  • No Firewall you mean Windows Firewall and Base Filtering Engine service on both DC and DPM server are disabled, correct?

    Do you have any NIC Teaming configured?

  • Hi Gai,

     

    So you are protecting servers on the same domain.

    ILO does not effect the backup as well as what kind of server. So lets leave these things aside.

    Now you said that you've seen error in VSS writers.

    Can you please go to the server. RUN elevated command prompt and run "vssadmin list writers" and check the status of each writer. The status should be "stable" otherwise restart the server and check them again.

     

    And please confirm that you have all local firewalls disabled.

    Hope that this helps,

    Laith

  • Do you have DHCP server role installed on these two machines?
    Thanks, Wilson Souza - MSFT This posting is provided "AS IS" with no warranties, and confers no rights
    Thursday, December 29, 2011 6:49 AM
  • Windows firewall is turned off by GPO.  The base filtering engine service is still running, should I disable this service for troubleshooting?  I'm not familiar with it and have never turned it off on any of our servers, including these two new ones.

    No teaming involved.

     

    Thursday, December 29, 2011 3:07 PM
  • All writers are listed as stable, with last error "no error"
    Thursday, December 29, 2011 3:09 PM
  • Yes, DHCP is running on both of these.
    Thursday, December 29, 2011 3:09 PM
  • This should take care of the VSS error but might not resolve your original issue.

    1. Download and install subinacl from the link below

       http://www.microsoft.com/downloads/en/confirmation.aspx?familyId=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displayLang=en

    2. Run the following command to export the current permission (savethe output to a safe location)

    subinacl /subkeyreg system\currentcontrolset\services\vss\diag  /display=sddl
    

    3. Run the following command to set permission

    subinacl.exe /Subkeyreg System\CurrentControlSet\Services\VSS\Diag /sddl=O:SYG:SYD:PAI(A;;KA;;;BA)(A;;KA;;;SY)(A;;SDGRGW;;;BO)(A;;SDGRGW;;;LS)(A;;SDGRGW;;;NS)(A;CIIO;RC;;;S-1-3-4)(A;;KR;;;BU)(A;CIIO;GR;;;BU)(A;CIIO;GA;;;BA)(A;CIIO;GA;;;BO)(A;CIIO;GA;;;LS)(A;CIIO;GA;;;NS)(A;CIIO;GA;;;SY)(A;CI;CCDCLCSW;;;S-1-5-80-3273805168-4048181553-3172130058-210131473-390205191) 
    
    

    And yes, stop Base Filtering Engine and test the backup.

    Note: Certify that you have other means to access this server (like ILO or locally) when stopping BFE. As there are other services that depending on it, sometimes these services stop but BFE does not. If this is the case you will lose server connectivity until BFE is completely stopped.

  • Sorry for the delay.  I wanted to be on site for disabling the BFE service.  I got out there at the end of last week and stopped the service, tested the backup again, and it is still failing. 

     

    I did also run the subinacl utility as directed, and have not seen any more of the vss error.

  • Are you running IPv6 on the network as well as IPv4?  I'm having a similar issue but the connections between the protected servers and DPM are more complicated (v6 using a v6v4tunnel over IPSec).  I read of issues where IPv4/IPv6 mixed environments can cause problems for DPM and I've only had my issue when I've been trying to leverage IPv6.

    This registry edit may be useful if you are running IPv6.

  • No, IPv6 is disabled on both the DPM server and the servers I'm having issues backing up.
