We have 3 domain controllers in our environment, two in our production site, and one in our DR site. The "primary" domain controller is in our prod environment, and serves as the time server.
As part of DR testing, we break the link between the two sites, and bring up replicated VMs.
When i tried adding client PCs to this DR environment, i noticed that the time was an hour wrong (I think this may have been due to the image being created during Daylight Savings Time, and being deployed after.
Anyway, I got around this by making the DC out there a time server. This worked perfectly. So, what i'm wondering is, can i leave this server as a time server, or will this cause issues with the primary Prod DC when the environments are re-linked?
