Installing OCS and creating CA's

Hi everyone,

I'm hoping that someone might be able to help me or point me in the right direction. I'm currently installing a trial version of the OCS software onto a server (W2k3) and I've come across something I haven't dealt with before - Certification Authorities.

I've stopped the install of OCS and currently going through the process of creating a CA on the OCS server. I'm given a number of different options to choose from: Enterprise Root CA, Enterprise Subordinate CA, Stand-alone Root CA, Stand-alone Subordinate CA.

Is there a better one to go with? After installing the CA - what happens if we decide not to go with OCS - can it be "un-installed" from the Domain?

Any information would be greatly appreciated.

Cheers ... Andrew
