URGENT!!--Workstations on Domain Cannot Comunicate with BDC

Yes, Well I’m running a Windows NT PDC, a Windows 2000 BDC/exchange server, and Windows 2000 workstations. When a workstation on the Server's Domain tries to communicate with the PDC everything is great. However, when the workstation try to communicate with the BDC it errors out. This is the result of any application i.e. Server Manager, outlook or even trying to get in to the server. The server communicates perfectly fine. And all NT workstations with accounts on the trusted domains can access the BDC fine. Event viewer displays no obvious errors. This set up has worked fine for over 6 months. This error just came up with no apparent cause.

Um... how did you do that?

Windows 2000 cannot be a BDC for NT.

Exchange 2000 cannot run without Active Directory, aka it can't run on an NT Domain.

NT cannot be a Primary Domain Controller for Active Directory.

well the BDC is running windows 2000 however it is running exchange 5.5. a registry entriy was made to keep the bdc from participating in elections. it was one of those things where this how it has to be done do it. it has worked fine like i said. but it doesn't now.
Chris DentPowerShell DeveloperCommented:

Okay.. the thing is. Windows 2000 still cannot be a BDC for an NT 4 Domain. It's just not possible to make it one.

Are you sure it's not just a member server?

ok i just double checked.. we are not running a Windows 2000 BDC. so we have two nt servers and the workstations are windows 2000. i am trying to access anything on the BDC. the only things i can do is ping and resolve the name. anything esle i try get a network path not found error.
Chris DentPowerShell DeveloperCommented:

Ahh okay...

Network Path not found is most likely WINS / NetBIOS Naming.


On the Server check the WINS server address. Then run:

nbtstat -RR

from the command prompt - this will Release and Refresh it's NetBIOS naming details in WINS.

On a workstation check the WINS server address is correct then try:

nbtstat -c

Again from the command prompt. This will clear out the local computers NetBIOS Cache.
