DOCUMENT:Q129858 06-FEB-2002 [winnt] TITLE :Error C00000BC When Changing Password in Trusted Domain PRODUCT :Microsoft Windows NT PROD/VER::3.5x OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - 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 <20> to find the primary domain controller (PDC). However, no domain controller registers <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 <20>, this problem occurs only when WINS or DNS server resolves the NetBIOS name <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: <20> - If you use DNS, delete the following entry: 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.
