I have discovered that I cannot telnet to the 1433 port on the db server which seems to indicate that it is not accepting connections for some reason. I used NetMon and discovered that I see communication from the app server to the db server but nothing ever comes back from the db server. This only happens when trying to connect to this cluster. I can communicate with all of my non clustered db's just fine. I don't know if there's something i've not configured correctly or what. I don't much experience setting up clustered db's but i've set up plenty of stand alones and usually this is caused by the protocols not being enabled or that or a named instance is not being accounted for but this is a default instance.

Any ideas why I wouldn't be able to telnet to 1433 with the firewall off?
