Whenever any of our users, who do not have administrative rights, attempt to access a page containing a RadCalendar control, they receive a 403 Access Denied message. We've checked our error logs and the following message appears each time this error is generated:
Application error when access /Company/News/Pages/default.aspx, Error=Access to the path 'C:\Inetpub\wwwroot\wss\VirtualDirectories\80\bin\RadCalendar.Net2.DLL' is denied.
The rest of our custom dll's in this directory are able to be accessed without any problem so we know that the permission levels on this directory are correct.
What could be causing the RadCalendar dll from being able to be accessed?
