After using the following document on my Issuing CA's; http://social.technet.microsoft.com/wiki/contents/articles/1559.how-to-configure-a-static-dcom-port-for-ad-cs.aspx, Once I set the Component Services->DCOM Config->CertSrv Request->Endpoints to 18300, I've found I cannot enroll in certificates I once was successful with. The error I receive from the endpoint is "The endpoint is a duplicate" within the computer-certificate MMC.
The local administrators group of the Issuing CA is the Owner of the HKLM\SOFTWARE\Classes\AppID\{D99E6E74-FC88-11D0-B498-00A0C90312F3.
Certutil Ping (certutil -ping MySubCA):
