DOCUMENT:Q167261 10-AUG-2001 [winnt] TITLE :Document Error: Replacing a Primary Domain Controller PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SUMMARY ======= The "Replacing a Primary Domain Controller," paragraph on page 4, Chapter 1 of the Windows NT Server 4.0 Resource Guide is incorrect. It states that, if the primary domain controller (PDC) is not available, you can install a new PDC and the PDC will create a new security identifier (SID) for the existing domain. This is partially correct. The new PDC will be created as a new domain, but the existing backup domain controllers (BDC) will not be able to synchronize with the new PDC. Promoting an existing BDC is the only working and supported procedure for replacing a PDC. Additional query words: reskit how to promote procedure ====================================================================== Keywords : Technology : kbWinNTsearch kbWinNT400search kbWinNTSsearch kbWinNTS400search kbWinNTS400 Version : WinNT:4.0 Issue type : kbinfo ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
