I have upgraded all of my DC’s to 2003, upgraded Exchange to 2003 (both from 2k), and have a freshly installed Exchange 2003 server (running on 2003 server) and another freshly installed DC (not upgrade). The original Exchange(2000)server was a 2k DC too. I’ve had problems removing the whole of backoffice from it, but the Exchange part doesn’t show up in system mgr on the 2003 Exchange machine.
Had a couple of issues with the upgrade: had to move the Administrator account out of guest groups, and PCIgina.dll had to be removed (for MSgina.dll) as Netsupport Mgr had replaced it.
Now, if I shut down that server – although I have 2 other 2003 DC’s on the domain(and the Global catalog is on one of the ‘up’ ones) people can’t log in when it’s down, and older Outlook clients get ‘Server request’ boxes popping up and can’t send mail. All clients are pointing at the new server (Exchange), as they’re able to send mail usually. Is there a way of telling a workstation to stop going to DC ‘a’ to authenticate and go to ‘b’ instead? It seems that the clients (ALL XP) try to use the old DC and can’t find the others!! They can be seen over the network, etc.
Am I missing something here? They shouldn’t be using SMB anyway, should they? It just means I can’t decommission the old DC – and more importantly – I dont know why!!!
Thanks in advance…
Mat.
