Can't install collectors on Windows core DC's

The collector would need to have the RSAT tools installed to get the get-ad* cmdlets in powershell.  It's in the add roles/features of server manager.  That allows for the remote collection of AD data.

We've also avoided installing collectors directly on DCs as LM is extremely TCP Port hungry, as is Active Directory.  Combining them on the same box is bad for both.  With the DC being the heart of any windows enterprise deployment, it's detrimental to the whole domain to use the DC for LM.
