Good morning!  I'm trying to add a SQL server host and am encountering an issue.  I've used the host name, the FQDN and the IP address with the same result:  when I click the save icon, I get the error:  "Problem in adding 'hostname' Host".

Any idea as to what I am doing wrong or if I need to do it differently? 

I'm running build version 10.7, build number 10072, service pack sp-10.7

Any help you can provide would be greatly appreciated.
