I have a problem with ghosted Vista Business laptops losing the Wireless connection defined on the master image. I have had to add the connection by hand as I handed out the computers. This has been a problem with both GSS 2.0 and GSS 2.5.

I could understand if the connection was tied to a specific user, but I can log on to the re-imaged computers with a domain admin account and add the connection and it will be valid for the other users on the computer,  or I can add it in a limited user's session and still have it active for all users logging in later.
The XP machines we have suffer from no such problem.

The connection is a silent (non-broadcasting) WPA-PSK (TKIP) connection, and I haven't the time or resources to implement a RADIUS-server solution at this time.

So realizing that this may not be entirely ghost-specific but may be more of a matter of how Ghost/Vista cooperates (or not, as the case may be), could anyone give me some pointers towards:

Is there some setting in GSS that will allow me to keep existing wireless connections after re-imaging machines?

Failing that, is there some way of adding a WPA-PSK (TKIP) connection to a number of clients at a time, say a group policy or preference or as a last resort a reg-file that I can run manually after first logon?

I've tried googling for various combinations of wireless connections and Vista and all I find is the manual step by step method, so it seems my google-fu is weak in this specific matter.
