Is there any way in a Windows Domain to have the workstations set the time from the server every hour? I tried using the at command with a login script but limited-users can't do it, because only admin users can run at with their login scripts, apparently.

You may want to modify the registry rather than using the method you described you above. Changing the time update interval of Windows XP Start the Registry Editor. Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ W32Time \ TimeProviders \ NTPClient \ Double-click the SpecialPollInterval value, and change the Base of the Value data to Decimal. Now change the Value data to the time interval you desire. The time units is seconds. The default value is 604800 seconds (seven days). To accomplish once-per-hour synchronization change the value to 3600 seconds. Close the Registry Editor. Obviously, you need to be careful whenever using the registry editor. I'm also doing some further research as to whether or not this same modification could be produced via group policy setting. I'll post back here if I find anything. http://www.glendaleit.com/dnn

"set the time from the server every hour?" Any reason for wanting to do this points to a more serious problem that is not being addressed. Here is a discussion of the time service basics. http://technet2.microsoft.com/windo... Here is one with group policy http://www.microsoft.com/technet/pr... Are you ready for where Microsoft wants you to go today?

Well my friend really wanted him time right to record his favorite TV shows with a TV tuner card. Anyway, is there a way to run a logon script as Administrator, so you put in admin things, not just anybody things?

look at this software -- Windows Time Server/Client named Network Time System, it can sync all client machines even every 1 minute.
