Cannot tunnel into Remote Desktop

Hi, I've been using OpenSSH to tunnel into my home computer
(previously WinXP) for a while now, but since upgrading to Vista, I
can no longer do so. Here are the facts:

* I have OpenSSH (OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007) setup
under Cygwin on a Vista Home Premium machine listening on 443

* I'm using Bitvise Tunnelier to connect to the server

* I can ssh into the machine without problem and can also tunnel
through to a couple of IRC servers, so both the SSH server and
tunnelling appear to be working.

* Remote Desktop is listening on port 3389, and the local IP of the
computer I'm connecting to is 192.168.1.2

* I have forwarding setup like so:
Listen Interface: 127.0.0.1:3390
Destination Host: 192.168.1.2:3389

* On the RD Client side I'm connecting to localhost:3389. "Always ask
for credentials" is checked. "Always connect, even if authentication
fails" is selected. "Do not use a TS Gateway server" is checked.

When I try and connect, I get the following message:

This computer can't connect to the remote computer.
Try connecting again. If the problem continues, contact the owner of
the remote computer of your network administrator.

This is what I get in the Tunnelier log:

14:30:40.040 Accepted client-side client-2-server connection from
127.0.0.1:2255 to 192.168.1.2:3389.
14:30:41.041 Server rejected our attempt to open a client-side
client-2-server connection - reason: SSH_OPEN_CONNECT_FAILED,
description: Connection refused.
14:30:41.041 Closing client-side client-2-server connection from
127.0.0.1:2255 to 192.168.1.2:3389, sent: 0, received: 0.

Could anyone offer any help in troubleshooting this issue?

Many thanks,

Charles
