The issue I described would prevent you from testing the ODBC connection within the ODBC Database Administrator in Windows. Basically if this connection works then using the DSN in Studio should work. If you are trying a connection string that might be a different problem. The DSN definitely works.

Thanks for the speedy response Dave!
I think I should clarify more.

If I create a UDL, or ODBC, connection on the MG Server machine to the SQL Server on the other machine it works fine.  I'm trying to create a connection to SQL Server from Studio via the ODBC FDO Provider and choosing the 'Connect to a database' and 'Microsoft SQL Server' and then specifying the credentials and proper connection string.  This is failing.  So I'm not sure what MG is doing differently to communicate with the SQL Server?

As for port 1433, that would need to be open on both machines for the 'handshake' communications, correct?  I wonder if that's the problem...

I have an instance in house where the connectivity fails because of a setting to do with the port in the ODBC configuration.

When setting up the ODBC configuration there is a button for Client Configuration, click this and uncheck the dynamically determine port. 1433 should be shown in a grayed out box.

That might be the issue.

Subject: [mapguide-users] MapGuide connection to SQL Server through ODBC

Hello all,
I'm trying to make a connection to SQL Server through ODBC using MG Studio.
This works fine on a local test system where MG server & SQL Server are installed on the same machine.

When deployed, MG Server is NOT installed on the same machine as SQL Server.
In this scenario, I can create a UDL on the MG server machine and successfully connect to SS with no problems.
However, when I try to create a data connection in MG, it fails with the following error:
response returned status code 502 (BadGateway)

It would seem that something on the SQL Server machine is blocking the connection request from MG.  So the question is, what is MG doing differently than a simple UDL connection to communicate with the SQL Server machine?
Any ideas, suggestions would be greatly appreciated.
