Good Afternoon,
We recently installed a certificate authority using windows server 2008 r2. There was an old certificate authority that had went bad and the role could not be uninstalled on the bad server. The new certificate authority works with windows 2008 machines but does not work with server 2003 machines. Mainly trying to get the domain controller certificate. At first it was stating that the rpc was unavailable for the CA. I tried to delete the remnants under the sites and services role of the old server. The error now it states that it can not find a certificate authority. As stated above the newer machines (Server 2008) can see the certificate authority and request certificates but older machines cant. Any assistance on what to do next will be greatly appreciated. Attached is the error I receive when trying to request a certificate through the CA mmc.
