If the logs are checked, you may find an error message similar to "The target principal name is incorrect".

Resolution

ENC Client is likely pointing to an incorrect or invalid FQDN that does not match the FQDN specified in the Alternate Subject Name portion of the client certificate on the ENC Server.

Run a command like the following to correct the issue:

encutilcmd client -state enabled -server <proper ENC Server FQDN>

If the command runs successfully you will see the following after hitting enter:
