Windows

Here is how I do this on a NT network.
On a single server (for you, the one with Internet access) I run a program called the JSS Clock Sync (free download at http://www.jarlsolidsolutions.se/)
This program will sync a Windows clock with an atomic clock once an hour. I just let it run on my server. It is on my PDC. For the following example, let's say my PDC's machine name is \\MYPDC.
Now, for my other servers, I have the following line in the logon script that my Administrative user account (the account I log into my servers with) uses:
NET TIME \\MYPDC /SET /Y

That syncs the server I am logging in with with \\MYPDC.
So, if you log into your systems once in a while, their clocks will be synchronize with the one server, and that oneserver is synchronize with a clock on the Internet.

hope this helps

Hope it will help!

I use a freeware program called NetTime. Put it on all your servers and clients. Run it as a service. Designate one or two machines to be the ones that go out on the net to retrieve the time from time servers of your choice (nettime will also find them on its own). Configure those two machines to "let other computers update from this computer", and then configure all other computers on the network to go two those two and update their time every 10 minutes or so. NetTime is very easy to use and configure.

In the NT Server Resource Kit, there's a util called timeserv.exe (I downloaded it from the MS ftp site). Read the info - it does all this by itself, wasn't written by MS (but they own it), and was designed for NT environments. For Win2k, check out the built-in w32time.
