Hi,
We're trying to implement new power saving techniques. One of these is
having all PC's in our network shut down overnight. However, users
have a tendancy to leave unsaved documents open, so it seemed
hibernation mode was our saviour.
But, we're encountering major problems. When the PC's are brought out
of hibernation mode after a few hours (issue doesn't seem to occur if
PC's are left in hibernation for less than this), a number of errors
appear in the application log in event viewer relating to networking
issues (event ID 1054/15). These include problems relating to group
policy processing and contacting active directory. It seems the PC is
waking up before the NIC or something, but I can't figure out what's
going on. Things tried so far:
- Enabling 'portfast' on switch ports
- Upgrading NIC drivers
- Assigning a static IP address
- Disabling Windows XP fast logon
- Disabling the NIC setting 'allow the computer to turn off this
device to save power' in device manager
- Dropping NIC speed from 1gbps to 100mbps
None of this has made a difference and I'm completely out of ideas. I
can't believe I'm the only person experiencing this problem. Has
anyone else any suggestions?
Thanks.
