Some of our servers have Domain Time II on them but we are having to make the possible decision to buy over 100+ licenses for Domain Time II or enable the windows time service.
The installation of Domain Time II was done a few years before I arrived and I am trying to figure out if there was a reason for it over the windows time service. I have been told that Domain Time II is more accurate that the windows time service but I want to see all the options.
We have our domain controller running server 2003. The other OSes in our environment are: Server 2008, windows xp, windows 7 and other windows 2003 servers. Would the windows time service have a problem working with these machines especially if windows updates were not always performed? I just hate to make a large purchase without getting all my facts straight. Any suggestions as to which one to go with and why would be much appreciated. Thank you.
