I manage a large number of SQL servers (~180) in a test lab environment. I have configured a Master Server and registered 3 target servers in the same domain to it. This works just peachy. My problem is that I cannot find detailed end to end steps about how to add SQL servers from other domains to the master. Oh, I find all sorts of hints about editting the registry, and proxy accounts, and yadda yadda, but nothing the clearly walks me though how to do this.
