Netlogon Does Not Replicate Case Changes In User Account Names

Article ID: 168590

Article Last Modified on 11/1/2006



APPLIES TO

  • Microsoft Windows NT Server 4.0 Standard Edition



This article was previously published under Q168590

SYMPTOMS

Windows NT User Manager allows a user account name to be renamed. However, if the difference in the New User account name and the previous user account is only in the case of the user account name, then the case changes in the user account names do not get replicated from the primary domain controller (PDC) to the backup domain controller (BDC).


CAUSE

The user account name in Windows NT is not case sensitive. As a result, Netlogon Service will not ask the SAM on the BDC to change the name. This is optimization in the NETLOGON service.

RESOLUTION

Use the following workaround to replicate the user account name case changes, from PDC to BDC.

For example, to change the name JoeSmith to JOESMITH, perform the following three steps:

  1. Rename JoeSmith to Testuser.
  2. Synchronize the PDC and BDC in the domain.
  3. Rename Testuser to JOESMITH and then synchronize the domain.

This will change the account name to JOESMITH on the BDC.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
