I found the solution for my sleeping trouble... well... the computer anyways...
running powercfg -energy
showed the \FileSystem\srvnet was preventing sleep -
I saw the MS folks saying to update the network adapter, and there was an update (wasn't showing up in windows update, just the right click update driver via manager), and that didn't work.
I even enabled the reg key for the 'allow sleep with remote opens' - and that didn't work..
Even allowed machine to enter sleep while streaming via the power cpl - didn't work
Finally went to:
Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings
And under media streaming - blocked all - and that did the trick! I don't know if there's another way to allow streaming and enable sleeping, but for now, beats running all night long after waking for a time update etc... :-)
Good luck -

On Windows 8 did not worked for me:
I've even left the homegroup, removed all media sharing (blocked), changed the property in power configuration to allow sleep while sharing media, added the powercfg /requestsoverride
No effect, PC does not sleep automatically. I have to press the sleep button (or choose it from the menu) every time. Super annoying
Additional info: with Win 7 ultimate everything was fine. I did a fresh W8 installation and now I have the issue
This trick is working fine also for Windows 8 Pro + Media Center PAck
It's really weird that simply editing the current "Power Plan" to "Allow the computer to sleep" under the node "Multimedia settings" \ "When sharing media" does not the trick ?!

I was getting the same message and my HTPC was not sleeping when it was supposed to. The Powercfg -requests mentioned a local device was requesting the system not sleep. After watching the TCP connections in Resource Monitor, I realized the system was talking to my TV.
I then remembered I had previously set the system up to be a media server for the TV, which did not work of course. When I removed it from the TV list of Media Servers, the problem went away.
AFAIS, the only way to disable this service is through the services MMC.
Run services.msc, select "Windows Media Player Network Sharing Service", double click it, and select for Startup type: DISABLED.
After that, no more \FileSystem\srvnet and Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings\Share media with devices is grayed out.
Gentlemen, please see a related topic that contains an automated solution allowing you to check if the srv service is locking your PC from going to sleep and restarting it to remove the lock and let the PC to sleep. Here it is: Windows 8 does not go to sleep - how to identify the device/app preventing sleep
I quote the automated solution from that topic (all regards must go to the original author, Luke Hamburg):
Ok, I wanted to post this in case it benefits anyone. After tearing lots of hair out over this for months on end, I never did find any "magical setting" that eliminated the problem for good. For a while the problem disappeared on its own, but then a few weeks ago it mysteriously came back. I was fed up and so I came up with a solution that fixes the problem for me. It's not the most elegant thing in the world but it has worked for me and if you follow the steps below, you should be able to set it up without too much trouble. Hopefully MS will officially address this (if it's even their bug which remains to be seen) but for now, try this out and let me know if it works for you:
1. create a batch file, name it "C:\Scripts\restart_srv.cmd" containing the following content:
if exist %logfile% goto begin
echo [%date:~4,10% %time%] logfile created>%logfile%
echo [%date:~4,10% %time%] srvnet check triggered>>%logfile%
openfiles /Query 2>NUL | FIND /C "INFO: No shared open files found" >NUL
if errorlevel 1 goto yes_opens
echo [%date:~4,10% %time%] no open files, proceeding to check for srvnet driver block>>%logfile%
powercfg -requests | find /C "[DRIVER] \FileSystem\srvnet" >NUL
if errorlevel 1 goto no_srvnet_block
echo [%date:~4,10% %time%] **block detected, restarting srv**>>%logfile%
net stop /y srv >NUL 2>NUL
echo [%date:~4,10% %time%] open files detected, not restarting srv>>%logfile%
echo [%date:~4,10% %time%] no srvnet block detected, not restarting srv>>%logfile%
2. launch Task Scheduler (taskschd.msc)
3. create a new task called "Restart srv" and set it up like the screenshots below (start at midnight, repeat every hour for 24 hours)
4. (this step is ** optional ** -- You only need to do this if you want to be able to manually kick off this task easily via a desktop icon)
create a new shortcut, with the following attributes:
- target=C:\Windows\System32\schtasks.exe /run /tn "Restart srv"
- run: minimized
- icon: %SystemRoot%\system32\SHELL32.dll (red NO)
5. Fire off the task manually (either by double clicking the shortcut from step 4 or by manually running the Task via right-click: Run from within Task Scheduler) and check the logfile created by the task (open %TMP%\srvlog.txt with notepad) to make sure it's doing its job:
Good luck and hope this helps some people who are paying needless $$ for their insomniac PCs! :)
Well this is the world we live in And these are the hands we're given...
A solution in another thread worked for me.
Take all the computers on the network out of the homegroup. Turn them all off. Boot your computer and re-create the homegroup. Add each other computer back in.
I did this and the "active remote client" hasn't shown up yet.
BTW I monitored the powercfg requests using the following batch file, run as administrator:
powercfg -requests | find " "
: Delay 30 seconds
ping 10.1.1.1 -n 1 -w 30000 > nul
* THIS MAY WORK !! * WIN-8
In the process of setting up a "task" in the "Task Scheduler," as described in this discussion, I noted that there were five or six scheduled "tasks" for backing up and or synchronizing documents, photos, etc. to various drives that were not on my PC. After looking at the script and description for these tasks I noted that they included the word SanDisk, Kingston, Seagate, etc. Disabled them (right side of the Task Scheduler window) and it slept a few times. Do this step with great caution BACKUP FIRST. At least turn on Restore and create a restore point. I then did a word search on the manufactures name of the offending scripts and DELETED them.
It Worked for me.
Some of these thumb drives, and MANY of the USB External HDD's have built-in S/W and I may have tried them. Seagate started just like a CD disk for a program when I plugged it in and that was the worse offender! Somehow it ended up where I do not want it. I KNOW I "un-installed" any thing I did not want BUT some programs do not uninstall nicely from WIN-8.
I take no responsibility if deleting portions of the registry breaks your PC - Especially if you do not back it up.
