"The problem is when I use the Launch Sametime Connect from the web page springfield.theconsortgroup.com the Sametime Connect client always has the wrong Host name i.e poohbear.theconsortgroup.com"
It remembers it from the last time you logged in. The Java Connect client saves it in a properties file on the local machine. What do you get if you go to a totally clean machine?
In your Server document, search for poohbear and see ifyou have't changed the hostname or network address totally.
