well, i've made a program, to adjust the registry settings,
it was a friendly fight between me and the admin,
it was stopped because it took too much work for him, as he is very busy...
have you tried regedit, alternate regedit (native registry editor)
or just plain running .reg files, too gain more acces?
or try internet proxies, sign up for a daily ip group, you get a site, and via that site you can go here.
or setup you're own proxy by hosting a serv on yor pc, with a proxy program?
we once had the pass of the admin, admin rights, acces too the surveillance cameras, remote pc switch offs, local admin's,
and we could do everything we wanted. but we stopped
(actually, i'm goin to work with him in 2 weeks (internship (stage in het hollands?))
you could email me for the prog if plain .reg's and registry editors don't work.
(if the alternate regedit doesn't work, try resource hacking it, and change the internal name, it's a way too block specific progs)
succes!
