Windows Time Server

[bigjrocksit]

I have an issue where some of my XP workstations are unable to update to the correct time. I know we have time servers here and found that we have 3 different sources that supply time services.

My question is this- How many time sources should I have running on the network, and with more than one source could this be the source of my problem?

thanks!

It depends; are you a pure MS shop where you have an AD domain? do you have Linux/Unix servers on your network? Typically in an AD environment, you have the server that runs the PDC emulator role synch with an external time source and the PDC emulator becomes the time source for your Windows domain (clients and servers). MS uses the SNTP protocol which is its own implementation of NTP.
Linux (even VMWare) and Unix will be either pointing to an external NTP server or a local one that replicates with an external server (it should not use Windows servers for its time services)
