Lawrence,
I'm still not able to run the Server Publishing Setup wizard after making ASRR. I still get:
The provisioning process is complete. Failed to create the signing certificate. This WSUS server cannot issue a self-signed certificate. To import a signing certificate into the WSUS server, use either the SetSigningCertificate(string, string) or the SetSigningCertificate(string, SecureString) method.
Anything else you can think of?
