first off you will need Timeserv from the NT resource kit, read the htm file and see how it works.

2nd, here is some really rough kic code that I found, that you run on an administrators computer that will install the service on to the workstations.

!!!You should use this just as a guideline for yout final code!!!

Do
$x=$x+1
SHELL "XCOPY C:\TEMP\TIMESERV.* {Workstation}\c$\winnt\system32 /y"
SHELL "XNET INSTALL \\{Workstation}\TimeServ /b:timeserv.exe /n:Time Service/LocalSystem"
SHELL "XNET START \\{Workstation}\TimeServ"
UNTIL X={Number of Workstations}

Any other questions, I would be glad to help
