Seems to be a permissions problem

With impersonate = true, the thread takes the identity of either:
- the anonymous IIS user (if it is allowed for the Web application and no
ACL restriction nor Web.config forces the authentication of a Windows user)
- the Windows user (else)

In any case, whoever is impersonated lacks the necessary permissions to the
web folders and the pages can not be compared / recompiled if necessary

Jose.

I setup web.config with impersonation="true". On our local server the
project works great. I did the same procedures on our staging server, but it
failed with an impossible error:

Server Error in '/' Application.

monitoring file changes.

Version Information: Microsoft .NET Framework Version:; ASP.NET Version:
Note! There is no text afeter the last colon! I copied all the text on the
error page.

I am impersonating my account, which is in Administrators group on the
staging server, and I have full access control to the myapp project
directory. Additionally, I also tried to give full access control to my
account on the %windir%microsoft.net\framework\v1.x.x.xxx\Temporary ASP.NET
Files, but the error persists. Actually this step is not necessary, since
Administrators already have full access control of the directories.

Can anyone help?
