title: windows 7 firewall blocks connection to named sql instance
body: <p>I want to connect to a named instance of sql server wich runs on a cluster. When I disable the firewall on my windows 7 client machine, I can connect. However, when I activate the firewall, the named instance cannot be found. A named instance of a different server, not on a cluster, can be connected with the client firewall on.</p>
  
  <p>How can I setup my client firewall so I can connect to the named instance that runs on a cluster with my firewall enabled?</p>
  
  <p>Note: What I can do is to disable firewall, connect to the named instance and re-enable the firewall again. After that the connection to the named instance works fine.</p>
