How to add a User-defined networkadapter property page for XP SP2

I have tested to add networkadapter property page to my networkadapter driver several times.(use other dll file as alternative)
As long as the Coinstaller dll was filled in register ,the property page worked well.however,when Selecting disable the connection,I just gets a system warning message–“It is not possible to disconnect at this time. This
connection may be using one or more protocols that do not support Plug-and-Play, or
it may have been initiated by another user or system account.”
