Hi,

I am not an avid .net user but am tasked with solving a problem our current production application is having (written by someone no longer here).
When going into the ASP.NET configuration and clicking the Authentication tab, a dialog box pops up saying:
Configuration Error
An error has occurred attempting to read the configuration system.web/roleManager. Could not load type system.web.configuration.RoleManagerSection

machine.config Line 76

----
In addition to this when I try to get to the .net application via the web we receive an error saying "Server Application Unavailable" and to look at the application log. The application log says "aspnet_wp.exe stopped unexpectedly" and also ASP.NET process identity does not have read permissions to the global assembly cache. I've been looking this up and trying various things to grant the correct permission, but it doesn't seem to be making any difference. I'm also not sure if all these errors are related. We have .net working on two other machines, one 2003 and one 2000. The one I'm trying is also 2000. We didn't do anything special to those to get them working.

PLEASE HELP!
Melissa
