SUMMARY
If you deploy Windows XP Professional-based clients in a Microsoft Windows NT 4.0-based domain, Microsoft recommends that all the Windows NT 4.0-based domain controllers run Windows NT 4.0 Service Pack 6a (SP6a) or later.



MORE INFORMATION
Windows NT 4.0 SP6a contains several fixes for NTLM authentication. Without these fixes, Windows XP-based computers in a Windows NT 4.0-based domain may experience domain or network connectivity and communication issues.

For additional information about the NTLM fixes that are included in SP6a, view the Readme file that is included with SP6a.
