Certificate error - Exchange server removes
Posted on 2012-04-03
I began to see recurring App log and Sys log error entries over the weekend on Server4 and Server5, both DCs.
The App log entries are:
6 CertificateServicesClient-AutoEnrollment, Automatic certificate enrollment for local system failed (0x800706ba) The RPC server is unavailable.
13 CertificateServicesClient-CertEnroll, Certificate enrollment for Local system failed to enroll for a DomainController certificate with request ID N/A from mailsvr.mydomain.com\CA Server (The RPC server is unavailable. 0x800706ba (WIN32: 1722)).
The Sys log entries are:
10009 DistributedCOM, DCOM was unable to communicate with the computer mailsvr.mydomain.com using any of the configured protocols.
The server mailsvr.mydomain.com was decommissioned when Exchange was updated. I suspect there is a old cert referencing mailsvr but I don't know enough about certs to locate and remove it, don't want to screw up Exchange.
Just need to know where to look and find the old cert. then I just delete it?
