CA's and Certificates for MOM or System Center OM

[Guest Jason]

I am having some difficulty understanding and configuring CA's for monitoring

ofdomains outside the trust realm. I have loaded Microsoft's Certificate

Services, and in reading the instructions have tried going to

http://<computername>/certserv but page cannont be found. I am not opposed

to using Verisign or Thwate, but not sure what I need. I am running Windows

Server 2003 R2x64 Standard.
