Server 2008 R2 Time

I'm running a virtual environment with VMware with a mixture of Windows 2008 and 2003 servers.  I have three domain Controllers running one domain.  For some reason my primary DC's time is 10 minutes off as well as all the clients.   I need to update the time and resync but remember if the time difference between the DC and the clients is more than X minutes this creates a kerobos problem ....

Can anyone give some suggestions on the best way of handling this as to not create an issue.

Thanks a million in advance ..

If this is hosted on VMware vSphere

1. Sync ESXi Host Servers with an external time source (or internal time server)

2. Disable VMs syncing with their hosts!

3. Sync AD Domain Controllers (PDC Emulator) with same time source as 1 above.

4. Sync Linux VMs with time source as 1 above.

Thanks for the great info ... !!!    We had gone through all the steps you'd listed and still didn't work.  In looking further we discovered a local policy on the PDC that was preventing it from using anything than the Local CMOS clock .........

THanks .....
