Virtual Server 2005 time drift

I have 3 XP Pro workstations running Virtual Server 2005 with 3 DCs (1 Ops Master + 2 GCs), 1 VPN, 1 WWW, 1 DB, 1 Exchange.  All the virtual servers are Windows 2003 and part of a domain (the entire domain is the 7 virtual servers and the 3 workstations).  I have all 3 DCs set to use tock.usno.navy.mil for their SNTP servers, but for some reason all the servers seem to be drifting backwards towards -10 minutes.  This wouldn't be a major problem except Active Directory requires a time difference of less than 5 minutes between machines.  I'm sure that the workstations, VPN, WWW, DB, and Exchange boxes are drifting backwards because of the 3 DCs drifting, how can I fix this?  I thought using net time /setsntp:tock.usno.navy.mil would fix it, but it doesn't.  Since the 3 workstations are drifting back as well using the Virtual Server host-to-guest time sync won't help.  What can I do?

As I stated rather indirectly the guest-host time sync feature already is disabled.
2003 time set up seems to have gone back to the crappy Windows NT version. Post the settings for the w32time registry entry and we'll have a look. I've actually stuck NTPTIME (http://home.att.net/~Tom.Horsley/ntptime.html) on my 2003 servers 'cos they don't seem to want to play ball like my 2000 servers do.
One thing you may want to try, which could help you in troubleshooting your synch issues is a 3rd party time app (http://nts.softros.com/).  You can download and try for free and it will provide you with stats of how often it adjusts the clocks.
