Error C00000BC When Changing Password in Trusted Domain

• Microsoft Windows NT Workstation version 3.5x
• Microsoft Windows NT Server version 3.5x

SYMPTOMS

When you attempt to change your user password in a trusted domain using TCP/IP, the following error message appears:

Unable to change the password on this account (C00000BC).
Please consult your system administrator.

CAUSE

When changing password in trusted domain using TCP/IP, the workstation searches for <domainname><20> to find the primary domain controller (PDC). However, no domain controller registers <domainname><20>.

If the workstation issues a session setup to this NetBIOS name, the session request is rejected, and the error message above appears.

Because there is no application or server which registers <domainname><20>, this problem occurs only when WINS or DNS server resolves the NetBIOS name <domainname><20> to a valid IP-address because of an erroneous WINS or DNS entry.

This entry can be caused by a client naming their computer the same name as the domain name. This seems to cause an erroneous entry in the Wins database.

WORKAROUND

To resolve this problem, upgrade to Windows NT Workstation and Server version 4.0.

To work around this problem, do one of the following:

• If you use WINS, delete the following entry: <domainname><20>



• If you use DNS, delete the following entry: <domainname>

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.5. This problem was corrected in Windows NT Workstation or Server version 4.0.
