In step 3. “HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer” change value to “1“

What value are we changing?

DNS errors…DNS ERRORS!! Arrr…got it working, so you can disregard my last post.

Now I’m cool, too!

I wanna be cool!

I’ve created a VM DC off my hyper-v host; it works and can get to the web. Created a 2nd VM, joined it to the domain. But I try joining the host to the domain, and get a “cannot find the path” error.

??? Thoughts?

Thanks, MS site was no help. I would never of thought of checking for time sync between Guest and Host OS.

Thanks again for the information.

Problem we’ve found is after the DC reboots, the Hyper-V puts in a half-ass entry for the NTP source, crashing the w32time service.

On client, in HKLM\System\CurrentControlSet\Services\W32Time\TimeProviders

delete the 3rd folder (not nptclient or ntpserver). Then start time service and it’s fine, until the next reboot.

Definately have the time sync with host option turned off, and it stays off.

Fred – thanks for the tip. That setting is hidden away and took some finding. MS were telling me I needed to edit each .vmc file..

Outstanding article. I found it after 2 hours of research and was exactly what I needed to send me in the right direction.

A very similar solution exists for Virtual Server 2005 users (like me). There’s a “Host time synchronization” checkbox under the Virtual Machine Additions section of each virtual machine.

Style is amusing to read, content is clearing an essential part of the “chicken and egg” paradox of a W2K8 core server parent and it’s subsequently starting virtual W2K8 child trying to be a good DC. It helped! Thanks a lot.
