Do to a Comcast issue I had to re-subnet a network from 192.168.0.0/24 to 10.1.10.0/24. Small network. 20 workstations all Windows 7 Professional. Server is 2012 R2 Standard.
For some reason is has brought the network to its knees. The server appears to be running slow but I can't find it. Task manager shows no CPU or Memory usage. No disk activity. Yet documents (Word, Excel) are opening and saving painfully slow. Red Xs on network drives. Just general slowness.
Can't find the problem. Any ideas?
