Server Registration. I need Help.

Hello everyone!!

I´m having an issue installing a new server. The version is 16.7.25. on windows 2016.

I need SMC to register the new server with fully qualified name ( so we can use an ssl certificate with wildcard.

The problem is that right after installing the server I open SMC and see that the name showed it is just the local name (server witout So I tried to register it with the FQDN. Apparently I did it right.

But when I try to delete (unregister) the server with the local name, I can´t. Attached screenshot for help.

So.....How can I accomplish all this? Please help....
