Starting OpenSSH client on a windows machine from a batch file

Hi,

First time poster; please forgive me any protocol transgressions.

I am using openssh to secure a Synergy (mouse and keyboard sharing) connection 
between two machines on the same desk.

I can start ssh fine if I enter the following command into a cmd promt or even 
straight from the 'Run..' dialogue:

ssh -f -N -L 24800: <ssh server>:24800 <ssh server>

With this port re-direction in place I then point the Synergy client at 
localhost and a secure connection is made and everything works fine.

To make the process easier for my users - for some of whom starting the command 
promt is a bit too technical - I would like to either have the secure 
connection run at startup or have a batch file for the user to click on but I 
cannot get the ssh command above to run like this.

Many thanks, in advance, for your time.
