I had all this fun back in September. This is a message I saved (thank you, Bill Mayo and others!):
I would suggest you read some of the articles that I'll link below, but I will try to summarize to the best of my recollection (without re-reading myself). What you are seeing in the registry is not necessarily in effect. When HKLM\System\CurrentControlSet\Services\W32Time\Parameters\Type is set to "NT5DS", the "NtpServer" key is ignored. The default operation in a domain environment is that all member computers use domain controllers for their time source. Among the domain controllers, the one with the PDC emulator role is authoritative--this is the one that you should set to sync from an external, trusted source. http://technet.microsoft.com/en-us/library/cc773013(WS.10).aspx http://support.microsoft.com/kb/816042/ http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/time_w32tm.mspx?mfr=true http://technet.microsoft.com/en-us/library/cc773263(WS.10).aspx -- Richard D.
