Oh yes. Good luck as there are many many holes like this.... The knowledge base article Jeff pointed out can very confusing. This will stop that explicit issue by forcing it to use IE.... Use a .reg file and backup/test first. ---------------------------------------------------------------------------- -- Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Folder\shell\explore\command] @=hex(2):63,00,3a,00,5c,00,70,00,72,00,6f,00,67,00,72,00,61,00,7e,00,31,00,5 c,\ 00,69,00,6e,00,74,00,65,00,72,00,6e,00,7e,00,31,00,5c,00,69,00,65,00,78,00,\ 70,00,6c,00,6f,00,72,00,65,00,2e,00,65,00,78,00,65,00,20,00,2d,00,6e,00,6f,\ 00,68,00,6f,00,6d,00,65,00,20,00,25,00,4c,00,00,00 [HKEY_CLASSES_ROOT\Folder\shell\explore\ddeexec] @="" [HKEY_CLASSES_ROOT\Folder\shell\explore\ddeexec\application] @="IExplore" ---------------------------------------------------------------------------- ------------- -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jeff Pitsch Sent: 02 March 2006 17:08 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Link in Outlook opens full desktop.

I just had somebody tell me they can have a link such as \\Servername\share and it will open up a full desktop. If anybody knows of a policy that would stop this please let me know.
