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.
