offline root CA question

Can someone tell me if it is possible to create a MSFT offline root CA in a workgroup, and not install any online subordinate CA?  
i.e. if I need to process a cert, bring the offline root CA online to process then take offline again. its a security requirement if you are wondering about the question.

I just need to know if this is possible with the CRL publishing etc

thx - S

It's possible (well, I don't think it will accept being in a workgroup, but you can give it a domain of its own, build it as a virtual machine in hyper-v, and shut the whole machine down when not in use)

However, while for issuing CAs in an enterprise, I usually recommend using the MS CA, for offline roots I usually recommend using the XCA standalone CA - this is self-contained (perhaps obviously, will need a webserver to host its CRL, but this can be shared with an issuing CA) and can be easily stored onto removable media and placed in a safe etc when not in use, if you want more security (the db is encrypted, however, and has no web interface, so can be part of your usual backup cycle, depending on how paranoid you want to be about it :)
