Firewall?

>This thing is really kicking my butt.
>I have installed SQL Express on Windows7 for a client.
>The webserver is on a remote computer and needs to connect to the database.
>I can't for the life of me make a connection from the webserver to the database.
>
>I setup the same thing for the client on XP and I had no problems but with Windows7 I am having no luck.
>
>Remote connections are enabled. Ports are forwarded. Windows firewall is adjusted (and now turned completely off).
>
>Any help would be greatly appreciated.
