I been called out to help a friend who has win 2K SP1 and
he tried to install a modem which according to the
literature was suitable only for for win 95/98. After he
had installed the software a message came up to say that
he did not have the Administrator rights even though he
was member of administrator group and had all the
privilages. So having logged in as an administrator same
thing happened. He now cannot uninstall the software or
the modem and he is locked out from all the administrator
rights. Has anybody come across this and do they have a
solution? Many thanks.
