Problems to see "Default Web Site" with a user who's not "..

Hi,

I had install IIS 5.1. If I work with a user who's "local administrator" I
see the "Default Web Site" in IIS console and I can modify properties.

I create a second user with the "read,write and execute" privileges in the
wwwroot. But It was not a "local administrator". But it's an Operator of the
Web Site and it's in the "administrator group" who can create en manage web
site . When I log a session with this user, I can't see the "Default Web
Site" in IIS?!?!?

With the same config in Windows 2000 and IIS 5.0, I can see the "Default Web
Site" with my user without "local administrator" privilege.

Do you know the difference between these two different setup and why I have
a problems in Windows XP? The security rules had change in Windows XP versus
2000?

Thanks!

JM
