Question : java.net.SocketTimeoutException on new SQL Server host

I've been running jdbc to a SBS 2003 server running SQL Server for a few years. This weekend, we put in a new Server 2008 box and moved SQL Server to it. Now my jdbc app is giving the following error:

Sorry, unable to connect with Database Server. Please try again later. Status: 0 The connection to the named instance  has failed. Error: java.net.SocketTimeoutException: Receive timed out.

My connection URL is:
jdbc:sqlserver://server\TRAVERSE105, user: user, pw:

I believe I am connecting on port 1433 and according to the firewall settings on the new server that port is opened. Is this a permission thing? Just to check, I've given this user sysadmin priv. Still no go.

Answer : java.net.SocketTimeoutException on new SQL Server host

check the database server is listening on that port
