Password Issue Domain Not Available

By jr_hearty ·
I have a single domain. The PDC is on subnet 192.168.100.0. The BDC is on subnet 192.168.101.0. There are two locations connected via a T1 for data. I have WIN and DNS servers at both locations. I can ping via NetBIOS name from any workstation on either side.

When a user's password expires on the BDC side, they cannot change it. They get the error "Cannot change password. The Domain is unavailable" I also noticed that I can't open the usermanger from a workstation on the BDC side although I can open it on the BDC.

Does anybody know what is happening here?

Thanks in advance.

If users attempt to change their password, they must be able to locate the primary domain controller (PDC). When the slow link is not available or the PDC is unreachable, users are unable to change their password.
NetBIOS Name Resolution Mode When you use a domain spanning into multiple sites, the NetBIOS name resolution mode should be set to m-node (broadcasts followed by name server) on all servers and workstations.
This setting ensures that a local (for example, on the same subnet) domain controller is always contacted first (for example, before trying to contact the PDC).
On Windows NT systems, the NetBIOS name resolution mode can be set to m-node with the modification of the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBt\Parameters
Value : NodeType REG_DWORD 4 (4 is for M-NODE)
