I'm running a new Vista machine, and as Administrator, I want to edit my hosts file, but when I complete the edit and try to save, I get: "C:\Windows\system32\drivers\etc\hosts was denied".

 

Here's the details:

 

When I set up the machine, I created only one account, ME, and a Guest account was also created.  If I go to the User Accounts panel, I see that the only two accounts listed are, "ME-Administrator", and "Guest-Turned off".  So, I'm set up as the administrator.

 

If I do a "Properties" on the hosts file, and go to the "Security" tab, I see three groups of users, who have the following permissions:

 

System-Full, Modify, Read and Execute, Read, Write

Administrator (VISTA_MACHINE\Administrators)-Full, Modify, Read and Execute, Read, Write

Users (VISTA_MACHINE\Users)-Read and Execute, Read

 

According to the permissions that the system shows, above, I, as Administrator, should be able to edit the hosts file.  Why can't I?

 

Thanks.
