I had a client ring in the other day, they have a three tier PKI solution on Windows Certificate Services, that I put in about a year ago, it has been running fine, but now they were seeing some errors.
Bad signing certificate on Array controller.
The following errors were also being logged;

I quickly ascertained that removing and adding the nodes, didn't fix the problem. On the OCSP server, launch an MMC session, and add in the Certificates snap-in for local computer. Do a manual enrolment, but in the details, set the issuing CA to one of the CA'sÂ that is displaying an error, (using the OCSP Responder certificate template). Repeat for each CA.
Now add each node, but choose 'manually select a signing certificate'.
Then assign the certificate, and choose the correct cert for each node.
