Error Message: A Controller for This Domain Could Not Be Found

This article was previously published under Q184538
When you attempt to add computers to a domain during Windows NT Setup after you have installed the updated Lsasrv.dll file (Lsa-fixi.exe or Lsa- ixa.exe) on the Primary Domain Controller (PDC), you may receive the following error message:
A controller for this domain could not be found.
The behavior occurs because the updated Lsasrv.dll file (Lsa-fixi.exe or Lsa-fixa.exe) implements the new registry item called RestrictAnonymous that restricts the use of Null NamedPipes. Windows NT Setup uses a Null NamedPipe for the connection to the server to verify the domain. The Null NamedPipe is returned with access denied because RestrictAnonymous has been used on the PDC.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
