I recently took over with a company and am working through various issues left by the previous sysadmin. The domain functional level is Windows Server 2008 R2. On the domain controllers I am getting this error in the event log every 6 hours or so.
Application Log Event ID 13
¿Certificate enrollment for Local system failed to enroll for a DomainController certificate with request ID N/A from PM-vDC-01.domainname.com\domainname-PM-VDC-01-CA (The RPC server is unavailable. 0x800706ba (WIN32: 1722)).
I would like to clear this alert. How can I go about removing references to the machine pm-vdc-01 which no longer exists (it was decommissioned before I started so I have no history of the device). Would it be necessary to create a new CA for the domain and will there be any repercussions by removing the CA reference. Lastly would it be necessary to create a CA for the domain?
