I have installed SQL Express 2012 on our windows small business server.
After installation, I recreated a database from a .bak file.
Then I tried to create a dsn from my network Windows 7 machine and failed.
Then I followed instructions to use SQL Server Configuration manager to configure a server to listen to port 1433 for TCP/IP connections
Tried to create dsn again and failed.
Then followed instructions to open a port in the Windows firewall for TCP access.
Tried to create dsn again and failed.
When I create the data source and then test it with Microsoft SQL Server Native Client 11.0, I get the following error:
Microsoft SQL Server Native Client Version 11.00.2100
Running connectivity tests...
Attempting connection
[Microsoft][SQL Server Native Client 11.0]SQL Server Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].

TESTS FAILED!
Has anyone else had this problem and if so, how was it resolved?
Thanks
