Which ports have to be open for scanning other Domains?

Hi Guys,
which ports and Services must be running if I want to scan a complete Domain?
I have the Domain-Admin Account, WMI and COM/DCOOM Services are running.
The only Problem I see is the Firewall running.., do we have to open some specific Ports?
Thanks for your help...
