CCM/Unity Workgroup/Domain Best Practice

[MMstre]

We have our Call manager set up in its own workgroup and our Unity server sitting alone in a domain. This is causing some obvious problems, but specifically DNS and NTP. My first question is placing the CCM and Unity servers on seperate workgroups recommended? The second question is the work around to resolve these issues???

This is very common. Most of my implementations have CCM in a workgroup and then the Unity's in the AD domain typically. So the Unity server would depend more on the DC in AD for NTP, or however all the other domain servers.

But you can add a common DNS server to CCM and Unity. So whatever all the other servers use. Or you can just put all of the appropriate addresses in hosts and lmhosts.

Currently DNS is running on Unity, and the CCM's are configured to use this server. However, they are not resolving. As for using the host file, some of the concerns are accessing the internet. Granted access will be limited or on an as needed basis, but it becomes a nuisance nonetheless.
