My client is a public school system in which we have migrated their entire network from Novell to AD. We have 2 DCs in the Central Office (dc01 & dc02) with dc01 serving as the DNS server for the district, and each school having their own server, which is also a DC.
At one school, some users (a couple of months after the migration) are experiencing super-long logon times (1 user actully tried to logon in the morning, and by 3:00 it still wasn't in)!
My question is this: I know that DNS on the workstations should point to teh IP of the server running DNS (in this case, dc01 in the CO), which they do. Should I make each DC (in each school) a DNS server and point workstation DNS there? Seems to me that would be unnecessary, but with the extended logon times, I'm at the end of myself.
