Cannot connect to a remote SQL Server instance using SSMS on a Windows 7 pc

I had the following problem: On my Windows XP pc I could use SQL Server 2008 SSMS to connect to our SQL Server 2005 production server, but when I tried to connect from my (newly setup) Windows 7 pc I got the following error:

Cannot connect to {SQL Server Instance Name}.

Additional information:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server)

To resolve the problem I did the following on my Windows 7 pc:
* Opened Windows Firewall
* Opened the "Allow a program or feature through Windows Firewall" page
* Clicked "Allow another program..."
* Selected "SQL Server Management Studio" and clicked "Add". Only Domain was checked.
* Clicked "OK".
