When I update Windows through Windows Update, SQL Server Express 2008 stops working

Question

In my scenario I have:

• A Windows 7 machine with SQL Server 2008 Express (Database Server)

• A Windows Vista machine with my software (Application Server) that reads and writes data to the Database Server.

Yesterday, after a Windows Update, my software is no longer able to access the database.

On the application server there is another program, and it accesses the same database correctly, there is also SQL Server Management Studio, and it accesses the same database correctly.

The only way I was able to reestablish the connection has been shut down the firewall on the database server.

On the database server firewall already exists a rule that allows the use of the 3 main ports used by SQL Server (1433 and the two others that i don't remember)

I tried to create a rule on application server firewall to allows my program to exit, but the problem is not that. In fact, as noted above, the problem is on firewall of the database server: turning it off fixes the problem.

Answer 1

I guess you need open more ports.
