Old, but still coming up in google searches. Here's the solution that worked for me:
Dynamic Port Allocation explained:
http://support.microsoft.com/kb/823938
How to: Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager)
http://support.microsoft.com/kb/823938
In case that dissappears:
To assign a TCP/IP port number to the SQL Server Database Engine
1. In SQL Server Configuration Manager, in the console pane, expand SQL Server 2005 Network Configuration, expand Protocols for <instance name>, and then double-click TCP/IP.
2. In the TCP/IP Properties dialog box, on the IP Addresses tab, several IP addresses appear, in the format IP1, IP2, up to IPAll. One of these are for the IP address of the loopback adapter, 127.0.0.1. Additional IP addresses appear for each IP Address on the computer. Right-click each address, and then click Properties to identify the IP address that you wish to configure.
3. If the TCP Dynamic Ports dialog box contains 0, indicating the Database Engine is listening on dynamic ports, delete the 0.
4. In the IPn Properties area box, in the TCP Port box, type the port number you wish this IP address to listen on, and then click OK.
5. In the console pane, click SQL Server 2005 Services.
6. In the details pane, right-click SQL Server (<instance name>) and then click restart, to stop and restart SQL Server.
