I hope someone can help me as my client is seeing red because of this. They have recently installed a Windows 2008 Std server as a simple file server as a DC as they experienced speed issues with their p2p network they had before, also, they wanted to increase security etc... Their existing computers are Winxp Pro. When they purchased the server they also got 1 additional workstation with Win7 Pro. Now, I migrated all their data, connected every PC to the domain, created scripts etc, as I always did before with server 2000 and 2k3, and another instance of 2k8. The issue is this: When the W7 workstation is left for a period of time, the network connection is dropped, the files they had open and were obviously working on cannot be saved etc. So a lot of info would either be lost or they would have to save it to the local drive, restart the PC and copy the new file back to the network shares. Simple networking yes, nothing fancy. I have browsed many other forums, support channels etc., and they all said a similar thing. 1st: Disable 'Allow windows to turn off this device etc...'. So I do this, restart the machine and it's back, re-enabled. hmmm... 2nd:Disable the PNP functions for that particular NIC in the registry by changing the figure from 38(default) to 18 or 8(which apparently disables (greys out) the power saving feature... Restart the machine and it's back. hmmmm... 3rd: Update Driver, retry above, no luck... My question is this, is the power saving controlled by the 2008DC? I checked all policies and all power saving entries are set to 'not defined' which in my and others opinions, mean not enforced giving the administrator full permission to change as he/she pleases on the local PC. But after trying all this, the W7 PC keeps reverting back to the same. Nothing mentioned in the logs, eventvwr or anywhere. I need help. Anybody, would be much appreciated. Leon p.s. why would any sane person enable power saving on a server? Were the WS2k8 developers smoking something at the time? It's there and I can't understand it, on this server I have the same issue with the NIC, but as the XP users are not affected, I am looking to sort out the W7 machine first. I had this posted in the Window 7 forum and was given a few suggestions to no avail, thanks to Niki Han for your assistance.

I do think power saving features are usefull on server systems. After all, a lot of servers are only moderatly used during bussiness hours and almost completey idle otherwise. In these cases it can cut powercosts when you plan and configure powersaving features. However, from your explanation, I do not think this is initiated by the Domain controller (as you never configured those policies and doublechecked that). However, you could use the policy result wizard to find out which policies get configured when a certain user is logged on to a certain machine. A local policy could be configurex (just start gpedit.msc on the local machine to review/configure this). Local policies are overridden by configured domain policies, so you can try to apply a domain policy with these items set to disabled. Was this a default windows 7 installation? or is this implemented as delivered by the suplier? Are there third party power management features installed (dell quickset for example?) I know som of these disbale the NIC upon inactivity or when no ower adapter is attached (laptop). Do you have to possibility to istall a second nic into the client to check it's behaviour? This might exclude hardware or driver specific issues. MCP/MCSA/MCTS/MCITP

Hi, Please post output of ipconfig /all to the forum. Have you installed the latest NIC drive on the affected computer?
