Re: com port access denied

In regular XP Pro the account was a member of both Administrators and Power
Users. But in the settings for the 'User Account' they are just radio buttons
and I can only choose one or the other; how do I set the account to be a member
of both? And I'd always assumed that Power Users were a subset of
Administrators so I thought that anything a Power User could do surely an
Administrator could do?

Have you tried a Power User account?

I've built a 'full-up' XP embedded system using Sean's component. We have
an
application that uses a number of com ports. I configured the com ports
in
XP Pro and exported the 'ports' registry branch and made a component for
them. The image has a 'user' account, in the administrator group as well
as
the Administrator account. When the application is run in the 'user'
account, it gets an 'access denied' return code (2) when trying to open
the
ports. But if it's run in the Administrator account, it works fine. What
other registry settings do I need to make to be able to access com ports
from
a user account which has admin rights?
