Testing SQL Server Connections
I found this gem today http://blogs.msdn.com/b/steverac/archive/2010/12/14/test-remote-sql-connectivity-easily.aspx trying to confirm if a windows server had access to a SQL instance (thinking I'd have to install something and do 10 restarts) - turns out you can create a .udl file which will bring up simple window to test your database connection!
Enjoy
