Question

Answer 1

Make sure that the date is set correctly on both the client and server computers (this can affect daylight savings) and that the time zones are set correctly on both.  Also, try pinging the time server from the clients (and see if there is communication).   Make sure the time server port is not blocked on your server's firewall settings.   If the computers use a domain controller, they may be looking at the domain controllers clock as a time server, so you may want sync your domain controllers clock to it.  Additionally, you may want to see if the time goes irregular with the computers off in the BIOS.  If this is the case, try replacing the CPU board battery in the clients that are affected.
