Windows server 2008 R2 Certificate Authority error event viewer

I am getting the error "The windows default policy module initialize method returned an error. The specified domain either doesn't exists or could not be contacted the error code is 0x8007054b. The active directory containing the certificate authority could not be contacted. " in the error logs, I have no idea why I am getting this error, The CA and the ADDS both are installed on the same server,inspite of that I am getting this error.

Any suggestions for trouble shooting...

Any luck trying this?

If you exported the self-signed root Certificate from the previous CA, you could create a GPO to automatically add this Certificate to every device's "Trusted Root Certificate Authorities". This would mean that any certificates signed by this CA will be trusted, because the root certificate is a trusted root certification authority. This will give you a bit of breathing room while you re-establish a new Certificate Chain.
