1) Exception Information
Exception Type: System.Runtime.InteropServices.COMException
Message: Cannot copy registry settings from the default Policy Module. Registry location: SYSTEM\CurrentControlSet\Services\CertSvc\Configuration\CONTOSO CA 01\PolicyModules\Clm.Policy.
Troubleshooting and Cause
In the event log the registry path from the error had the CA name of CONTOSO CA 01. The CA name was actually CONTOSO CA 01A. The certificate services were originally installed as CONTOSO CA 01. The server was subsequently reinstall with the CA name of CONTOSO CA 01A. There was also an HSM attached to the CA.
The crux of the problem appeared to be the CM policy modules being written to the incorrect registry path, using the old name.
Much troubleshooting was done to discover from where the incorrect CA name was being found and put into the registry. Using verbose MSI logging along with Process Monitor logs the FIM CM module installer never referred to the incorrect name. While exonerating FIM CM the culprit was still undiscovered.
Research found that the CA names may be obtained from active directory. A search of the Enrollment Services container in AD uncovered two pKIEnrollmentService objects. One object with the original (undesired) name and the current name exist in the container.
CN=Enrollment Services,CN=Public Key Services,CN=Services,CN=Configuration,DC=contoso,DC=com
- CN=CONTOSO CA 01,CN=Enrollment Services,CN=Public Key Services,CN=Services,CN=Configuration,DC=contoso,DC=com
- CN=CONTOSO CA 01A,CN=Enrollment Services,CN=Public Key Services,CN=Services,CN=Configuration,DC=contoso,DC=com
Removal of the invalid pKIEnrollmentService object alleviated the issue. As long as no active CA object is removed there should be no CA issues. Only an orphaned object was removed.
