I too have had problems with this. When trying to register KixGUI.dll I get 0x80004005 which seems to be 'Unspecified Error'. Under NT4 the dll can be registered by a non-admin user no problem, but W2k wont allow it.

I would like to avoid any embedded admin password type solutions (for the time being anyway).

Is there a right or reg key that can be changed to allow non-admin users to register dlls on Windows 2000 workstations?
