DOCUMENT:Q184538 10-AUG-2001 [winnt] TITLE :Error Message: A Controller for This Domain Could Not Be Found PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS:kberrmsg kbWinNT400sp4fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server, Enterprise Edition version 4.0 - Microsoft Windows NT Server version 4.0, Terminal Server Edition ------------------------------------------------------------------------------- SYMPTOMS ======== 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. CAUSE ===== 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. RESOLUTION ========== 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, please see the following article in the Microsoft Knowledge Base: Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack STATUS ====== Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4. MORE INFORMATION ================ For more information about the updated Lsasrv.dll file (Lsa-fixi.exe or Lsa-fixa.exe), please see the following article in the Microsoft Knowledge Base: ARTICLE-ID: Q154087 TITLE : Access Violation in LSASS.EXE Due to Incorrect Buffer Size ====================================================================== Keywords : kberrmsg kbWinNT400sp4fix Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT400search kbWinNTSsearch kbWinNTSEntSearch kbWinNTSEnt400 kbWinNTS400search kbWinNTS400 kbNTTermServ400 kbNTTermServSearch Version : WinNT:4.0 Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
