DC: Virtualized and External NTP servers (June 16, 2008)

Friday, January 8, 2010 at 12:32AM

The following two discussion points arose today again for what feels the 100 time:

Why Don't you recommend Virtualized DCs?

Why Can't we point our domain DC to our network NTP servers – why should we set it to an external time server?

Virtualization first.

1. Performance.

2. Support (3rd party)

3. The possibility of a USN Rollback due to the guest machine being set to the time (date) of the host and the host undergoing a in accurate time change (BIOS update/reset or accidental change).

4. There is also the possibility of a the loss of backups of AD by those thinking that snapshots of DC in a virtualized environment is an appropriate method for doing so. Again making a snapshot will capture the USN of the DC that is previous to the USN of DC as now know to other DCs in the Domain. This is why a supported backup method (NTBackup is the easiest) is required.

NTP next.

Again USN is the reason – what happens if the NTP server gets reset due to a firmware update or accidental change? You’ll be in the same boat. It’s not to say that external time server’s can have this happened – but most well know internet time servers have very tight controls and fail safes placed on them.

Again you can do both – just be conscience of the fact that you may need to know how to do an Authoritative Restore of your Domain
