Synchronise time on NT4 server

[Teamaker]

Does anyone know of a tool to synchronise NT4 servers with an external internet clock? and if so does it have to be installed on all servers of just the PDC.

"Atomic Clock Sync" is a nice free piece of software that does the job. You would only need to install it on the Server that the Workstations get their Time from.

PS: the website you can get it from is

Our firewall doesn't allow this utill to work is there any other way, or just a way to stop out NT servers going out of sync within the domain. (Make them all sync with the PDC mabe?)

 

[Grenage]

Well there is always the Command Line:

NET TIME \\SERVERNAMETOGETTIMEFROM /set /yes

Having this on a login script, although I don't see how they would go out of synch unless they were updating indepentantly from another source.

Or you could enable the NTS port (Port 37) for outgoing connections only ?

Sorry i was unclear, the proxy is in it's own domain and it seems to go out of sync with the servers in the other domain this means that the internet filtering software comes on too early and goes off too late.

 

[Grenage]

Ah I understand. Well the above command line in a batch file should do it, if you tell Windows Scheduler to run it every 24 hours or similar it should keep it up to date with whatever server you choose in the command line.

Ah thanks that worked a treat.

I had tried that before but

NET TIME \\SERVERNAMETOGETTIMEFROM /domain /set /yes

which didn't seem to work.

the atomic clock software that grenage posted about blew me up the wazoo, set my network back a day, twice, got rid of that util quickly...

be wary if you are planning to use it.

You can also use the TimeServ.exe from the NT Resource Kit. Set the time correctly on one server and install the service on all others. Modify the ini file on each to point to the "PrimarySource" to get the time. This updates the time on each machine automatically daily.
