Hey,
I have a customer running a Windows Server 2008 R2 HyperV VM which serves up a SQL database for a Sage ERP application.
The customer wanted me to import a second database from another, external Server.
Problem was: The database was hosted on a MS SQL Server 2008 R2 instance, the customer is still on 2008 sans R2.
Since, unfortunately, the customer wasn't willing to invest in a new SQL Server and Setting up a separate Windows VM was no Option either I had to make do and install a second SQL Server 2008 R2 Express instance alongside the existing SQL 2008 instance.
Since the Default TCP/IP port 1433 was already in use by the 2008 Standard instance, I went ahead and set the port for the Express instance to 1450 and made sure to open this port in the Windows Firewall.
I restored the database and was able to succesfully Login using SQL Server...
