Disable the homepage from auto appearing as desktop when active desktop is enabled?

Hello

I have numerous desktops running windows XP who's users have a policy

puching out corporate wallpaper, which requires active desktop to be

enabled.

The same users logon to a Win2k terminal server, and active desktop (with it

being enabled for the user account) gives every user the homepage when they

logon. Is it possible to have this feature disabled? I think it must be in

the default user profile somehow but unsure, can someone help?

Thanks
