If you are talking about a special admin variable, do yourself a favor and look up list... someone with a save editor can modify the value easly and become admin.
Anyways, you can either use client/New() [when a player just connects to the game] or mob/Login() to check and set out the special windows.
And the proc you should use is... winset()!
winset(mob or client,"Window.ID.Here","window-param = here")
But if you just want to show/hide it, there's the easier winshow()!
winshow(mob or client,"Window.ID.Here",Any value [including null/blank] EXCEPT for 0 here shows the window; place 0 here to hide the window)
If you ever decide to do winset() and want to know the list of params, go to your 4.0 DM and Help > Skin Reference
