We are attempting to configure a server application to run on Windows Server 2008 R2 using SQL Server 2012 Express. With the server firewall turned off completely the application can communicate just fine with the server, but when the firewall is turned on and the usual SQL Server ports are enabled, the communication fails.
Are there any special tricks with the firewall to enable this to work on a Workgroup network? The application support people are used to working on a domain-based network and are surprised that the firewall is not working with their usual ports open.
We were given the following batch file to open up the required ports on the server. We tried this and saw all the corresponding SQL entries in the firewall exception list, but it was still not working (and we did try a server reboot).
