Certificate Authority on Active Directory 2003 PDC

Last Modified: 2012-05-06
I have discovered that we have a CA running on our GC server. Does anyone know if there are any default certificate dependencies ionvolved in a 2003 native forest? I can see that we're also doing IAS for wireless and VPN autentication and so the certs may be for a combination of that and other IIS certs but..... I'm afraid to move it to a new server. SOme of the certs appear to be issued to other AD integrated DC's. I can't remember if AD uses certs for anything or if it was all added after the fact. Second question: does a CA and or IAS need to run on a DC for any reason? Thanks to all!!!

Thanks Laura. We are repsonding to a forced migration of all servers from one subnet to another. Therefore all servers (includign DC's, Radius, email, etc) are changing IP addresses. In this process, some are being virtualized into ESX using the VMware converter while others are being replaced by new Guest Operating systems and then having all of their roles rebuilt or transferred over. Yes part of my requirements are definitely to find out where/why all of these certs are being issued. One perplexing thing is that the CA is issueing certs to other DC's on a regular basis. I'm not sure why or quite how to pursue it in the time I have. I guess I'm searching for tribal knowledge to shortcut the process but also I'm trying to figure out what dependencies exist natively between AD and a lcoal CA. I thought I remembered runnign a new forest with no local CA at all. Doe sthis wash? I appreciate your time.
