All SQL Servers in the PowerDNN network run on the standard SQL Server port of 1433.  Sometimes, when trying to connect to your database, you may receive an error like this:

------------------------------
When trying to connect with SQL Server Management Studio I get an error
message that stats SQL server does not allow remote connections.
------------------------------

If you receive that error, that means that your ISP (Qwest, ComCast, Cox, RoadRunner, Verizon, etc) is blocking you from connecting to SQL Servers.  In order to resolve that problem, you will need to conact the company providing you with internet and have them unblock port 1433.

Your SQL Server's domain name is always MSSQL.YourDomain.Com.  So, if your site was Foo.com, your database server would be MSSQL.Foo.com .
