clock not in sync with servers

Try using Tardis along with K9 found
at http://www.kaska.demon.co.uk/

Your server will send out NBT time broadcasts
on your subnet and the K9 application will sync your desktops to your server.

If youre using logon scripts try this line:
net time \\servername (or /domain) /set /y

\computername
Specifies the name of a server you want to check or with which you want to synchronize.

/domain[:domainname]
Specifies the domain with which to synchronize time.

The /y
Confirms the time update, whitout the users help

BUT remember that the users must have the rights to adjust the clock on their machines.
