A few weeks ago I demoted the Main DC server using DCPROMO.
The hole demotion went smoothly with no errors.
But now I'm gettin alot of users reporting their systems are slow in general.
There is only 1 DC in the building, this is also the File server, Exchange server 2003, DNS, DHCP and WINS Server.
Logging in seems to be a bit slower but not too bad, it's generally browsing/opening and saving files on the file server. Also opening, creating and saving emails are being reported as taking alot longer than usual.
I've checked the task manager than the most percentage of the network connection in use i've seen is 7%, The most use of the CPU use i've seen is 30-40%.
The DC is a Dell Poweredge 2800 running Windows Server 2003.
Please advise me on where to look or what to do to find out and resolve the cause of this network slow down.
