Question : Certificate Blues

MS Server 2008 can't get a DC certificate due to the following error

Certificate enrollment for Local system failed to enroll for a DomainController certificate from xxx.xxx.com\Main CA (The RPC server is unavailable. 0x800706ba (WIN32: 1722)).

This is received after trying to request via the Certificates mmc, however when I use Web enrollment, I am able to request and receive a valid administrator Cert.
