"You cannot run the explorer using "run as". Anybody managed to do that?"
From Peter Torr's blog ( http://weblogs.asp.net/ptorr/archive/2004/03/21/93352.aspx )
"you can run Windows Explorer (and the related control panel applets) from your Admin account as long as you've set the "Run Explorer windows in a separate process" option from the admin account. Run regedit from your Admin console, navigate to:
HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Explorer\ Advanced
and set the SeparateProcess DWORD to 0x01."
