Netlogon Service Does Not Start After Applying SP4

• Microsoft Windows NT Workstation versions 3.5, 3.51
• Microsoft Windows NT Server versions 3.5, 3.51

SYMPTOMS

The Netlogon service on random platforms does not start after applying Service Pack 4 (SP4) for Windows NT 3.51.

MORE INFORMATION

When the Netlogon service tries to add itself to the Administrator's group to start up, it hits a condition that keeps the Netlogon service from starting. This occurs on the first restart after applying SP4. Although the security accounts manager (SAM) is apparently upgraded to its new format, the condition described above prevents the upgrade from taking place, rendering all further access to the SAM impossible. De-installing Service Pack 4, even when it preserves SAMSRV.DLL, does not fix the problem since the SAM itself has not been upgraded properly.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
