Time Synchronization in Windows

Posted on 17 May 2005

This week, I had a chance of playing Time Synchronization in Windows. I tried NetTime, an Open Source implementation of SNTP protocol. What makes it wonderful is the capability to be Server and Client for SNTP.

Installation is very easy, thus I am not putting in this blog. If you are using WinNT or Win2K, I strongly recommend you to install NetTime a service (but remember, you need to log in as an Administrator when installing).

Since I need to use NetTime in a corporate environment, I set up 3 PCs acting as NetTime Servers. Nothing special with the PCs, it must have an Internet connection and the PCs must be online 24 hours x 7 days a week. BTW, since it uses SNTP, then you may need to open Port 123 for outgoing connection.

My approach of source SNTP Server for the internal server is:

Then my approach of source SNTP Server for the workstations is using all 3 internal servers as the 1st, 2nd, and 3rd SNTP Server.

Although NetTime is no longer in active development state, but I think it is a fine implementation of SNTP in a simple package that NTP novices should have no difficulty with.
