CCSVM setup.

Hi, 

Im trying to install a ccsvm on virtual machine - windows server 2012 ( 500 GB, 8 GB RAM, Quad core )

- is it necessary to keep the ccsvm out of domain? 

- if im installing ccsvm outside the domain, what user credential with what priviledges should be created so that I can scan all my servers ( virtual and physical ) or do I need to add credentials only for scans?

- what all vulnerabilities can I initially look forward to remediate, how to prioritize?

Appreciate your help.

Thanks

Sikks.
