During an installation of SCVMM 2016's SDN feature, we're seeing this error message in the SlbMux Event Log:
Unable to validate remote certificate with thumbprint <Thumbprint> Reason: Remote Certificate is Not Authorized.
In our SDN deployment, we're using self-signed certificates. We've copied over the public portion of the Certificate into NCCertificate.cr and TrustedRootCertificate.cr and used the latest VMM SDN Service Templates available on Microsoft's github SDN repository. I've checked in the Cert:\LocalMachine\Root stores and we do see the Network Controller's certificate present in the certificate store.
Looking at the documentation, it tells us to "Fix the certificate issue", but what certificate issue needs to be fixed in this situation when we're using self-signed certificates and clearly the Network Controller's Self-Signed certificate is in the Trusted Root Store?
All posted advice may not be all that accurate. As always, test it in a lab before you try my advice! Best of all, the documentation is your friend.
