srvnet prevents Windows 8 computer from sleeping
Issue
Computer never enters sleep mode on its own. A user can manually press the sleep button and it works fine, but PC never enters sleep / standby as specified in power settings.
Troubleshooting
Running powercfg -requests at the elevated command prompt revealed that computer is prevented from sleeping by srvnet driver.
srvnet is related to network sharing and media streaming. That was strange as this computer was not acting as any kind of media or file server (although it was accessing some network shares via mapped drives). Media sharing via HomeGroup was also disabled.
Computer randomly wakes up from sleep
Issue
Computer wakes up from sleep / standby mode without any obvious reason. Very often this happens just few seconds after computer enters the sleep mode.
Cause and Resolution
Issue was caused by Intel Ethernet Controller (integrated LAN card) option: "Wake on Pattern Match". Disabling this option resolved the issue.
To do this:
- Open Device Manager
- Right click on your primary Ethernet Controller and click on Properties

Windows loses drive letter after reboot
Issue
Windows 8 loses a drive letter after every reboot. Adding the drive letter manually via Windows Disk Management works fine, but this needs to be done after every reboot.
In addition, VMware Desktop wouldn't work reliably with VMs saved on that particular hard drive. It would fail to create a snapshots or even open a hard disk tab in VM settings. Error would be something like "one of the parameters supplied is invalid".
