Required Permissions Cannot Be Aquired :-(

Hi everyone,

If anyone can help me with the following - I would be VERY grateful.

I need to deploy an 2 ASP.net applications that I've been creating onto
one of our live servers. Both applications use the Microsoft Enterprise
Library dlls and have them located in their respective bin directories.

Everything works fine on my development machine.

Now that I'm deploying it I've created 2 Virtual Directories to host the
apps. The first application runs no problem. The second, which is using
the exact same dlls is crapping out complaining about permissions with
one of the dlls (the one called ObjectBuilder.dll). I don't understand
why one V-Dir works and the other doesn't...

If anyone could advise me on what I need to do, or why its happening I
will be their best friend forever :-).

The full exception report is below

Many thanks

Simon

Hi Simon,
I'm experiencing something very similar. Did you ever find a solution...?
Cheers
