Click on Administration and Reporting -> Software Publishing -> All Packages, and then run the Server Publishing Verification Wizard from the Actions pane on the right. Do all of the servers that are listed when you run that wizard come back with “This server has the required certificates for publishing…”?
If not, you can then run the Server Publishing Setup Wizard, select your WSUS server from the drop-down box, and choose the option to “Distribute existing WSUS signing certificate to required servers”, and choose your EminentWare server to receive it.
If that does not resolve the issue, please let us know at firstname.lastname@example.org, and we can schedule a meeting to look at it together.
Yes, it comes back with the message saying the server has the required certificates for publishing.
