Fellow Experts, I need help.
Long story short - I've recovered domain controller from the crash and some time after the operation CertificateAuthority started making errors (Event ID: 22, just like below). Unfortunately we have only one server and had to put everything in one box.
Active Directory Certificate Services could not process request REQUEST_NO due to an error: ERROR 0xc8000152 (ESE: -338). The request was for DOMAIN\user_account. Additional information: An error has been encountered while analyzing the request.
...or the last message may be:
Error Verifying Request Signature.
I'm not sure about the exact message as I'm not using English Windows.
It happens for user accounts as well as computer accounts.
I've checked MS KB about the issue (with verifying certificates and generating new CRL list) and it seems everything is fine...
What may be other steps to look for?
In the worst case scenario I can decommission CA and start from scratch as it's not yet widely used (only for RemoteApp).
I have to admit I had some problems with AD, but it seems they're resolved by now - no reports of inconsistencies or any other errors...
