All Vista PCs in Office Suddenly Rotten Performance
Posted on 2009-06-30
Very odd one for the Vista experts:
-Large network, 95% Win XP, 5% Vista.
-Yesterday morning we lost power briefly where it went off and then on again real quick. Server room with all servers and network infrastructure is protected by UPS so nothing went off line there but offices/cubes lost power - so machines went down.
-Windows Vista users are reporting crappy network performance: takes 5 minutes after reboot for the "Welcome" screen to go away; once up, they can access some network resources but not others; internet access is spotty and slow; name resolution is VERY slow; they can't ping the DNS servers even though one of them is also doing DHCP and handing out the addresses; if they ping internal network resources by IP it takes 30 seconds for the machine to even start the ping
Here's the weirdness:
-ALL XP users are fine
-ALL Vista users are reporting the same issues where before the power outage they were all fine
-If there's more than one machine (1 vista, 1 XP) in a cube or office and there's a little desktop switch providing multiple ports, the XP machines run fine while Vista is awful.
-If we launch VMWARE Workstation on the Vista machine and starting up an XP guest, the XP guest performs fine EVEN AS the Vista host performs awful.
What in the world could have caused this and how do I fix it? It has to be OS specific but I cant imagine what it could be when prior to the power outage all Vista clients were running just fine.
