My client uses a non-standard SQL port number.
So for example, when connecting in SSMS (SQL Server Management Studio), we type in “MyServer,1234” for the server name. This also works in connection strings (i.e. specify servername, then comma, then port number.

I suppose if you were using a named instance, it would be “MyServer/MyInstance,1234”.

But if you are using WCF/SQL Adapter, it’s a little obtuse, you must specify the port number in the “InstanceName” property field, even though you are not using an instance:

Specifing port number for SQL Server (in WCF/SQL Adapter for BizTalk)

Type a comma, followed by the port number in the instance name.
