When trying to add unmonitored DCs to a pool, it fails as the site for the DC cannot be determined. If you view the list of unmonitored DCs in the Analyzer module, there are no statistics (such as number processors, site, etc) shown.
When trying to add a pooled agent, the following errors may be shown when the list of DCs for the domain is generated:
Domain controller <DCName> was not added because no site information was provided.
An error occurred while attempting to get the site information for <DCName>. The error returned was The server is not operational.
