I have a 1 year old SBS 2011 server. While trying to renew a certificate thru the SBS console, the wizard failed. I have event ID 100 logged with the message: AD certificate service did not start: Could not not load the current CA certificate. <server> Keyset does not exist 0x80090016. I can not manage any certificates thru the wizard or the MMC snapin. How do I regain control and renew the servers self sign certificate?
