+1, used that doc a couple months ago myself to correct a drift I was getting by letting Hyper-V supply the time to guests. Doing those sets fixed me right up!

This kept causing the time to go back and forth and it turned out the ESX systems were getting skewed from the NTP source at a greater rate. So let the domain do its thing with the servers by setting time.

The 2008 R2 server runs faster. Watching the clock it actually tickets about 3 real seconds to 5 seconds on the clock in the console. Needless to say this puts stuff out of sync pretty quick. Looked online and I found a few posts regarding some weird time services, but nothing Microsoft or VMware. Anyone seen this before? The 2003 Server runs normally. I can resync against the DC and they are out of sync by 15 seconds in under a minute. Greg Sweers CEO ACTS360.com<http://www.acts360.com/> P.O.
