NTP time on 2008 domain controllers is off by 2 minutes fast

Our 2 DCs time is set for the atomic time clock, but the 2 DCs are always running 2 minutes ahead. Our deskphone also use the atomic clock and they are right on with it. So may question is why do the Dcs run 2 minutes fast and how can I resolve this?
By the way, these 2 DCs are VMS running on ESXi 5.1

I believe the time is determined by the ESXi time and not an atomic clock, just a hunch.

the time on the esxi host are 2 minutes slower than the DCs. That's what I mean the Dcs are running 2 minutes faster for some reason..

Hmmm ... W32time, the timekeeping service in Windows. I experienced enough trouble with that piece of crap when in NTP mode to avoid using it whenever I can.

My recommendation:

Use a Windows port of the classic *ix NTP service on your DC VMs, and sync 'em with NTP time sources from pool.ntp.org. Ensure to disable the time sync features of VMware (to timekeeping services on one clock will cause time chaos). The NTP service software is free. Easy to install and configure, works like a charm and is stable as a rock. And it is nicer when it comes to one of the rare cases of troubleshooting.

See my article on NTP basics for the "How To".

The NTP service has a low ressource footprint, therefore the NTP functionality could be hooked onto existing machines or VM's like webservers, ftp servers, mailservers or database hosts - even in a DMZ - without visible performance impact.

If securtity is an issue, you might as well use local radio controlled clock appliances (see the article for that, too) in your LAN who serve times very reliable and precise.

Ok dumb question...
I think someone made some changes to the time entries in the registry for my second dc. So my question is, what should the registry entries be for time on the dc that is not the NTP?
I need to set this on the other DCs which are not supposed to be the NTP

That would be the registry entry for the w32time section
