ASP.NET doesn't have permission to access resource

[Brent Bigler]

The computer: W2K server, domain controller, Microsoft.Net Framework 1.1

=============== =========
The error message:

Access to the path "c:\fanmail\new files" is denied
....

Exception Details: System.Unauthor izedAccessExcep tion: Access to the path
"c:\fanmail\new files" is denied

*(see below for Stack Trace)

=============== =========

Fixes tried (but didn't work):

1. Added ASPNET account to c:\fanmail\newf iles and granted full permission
to resource;

2. Added ASPNET to Administrator group;

3. Changed machine.config processModel username setting to "SYSTEM";

4. Changed machine.config processModel username setting to "{Domain}\ASPNE T"
along with the password setting to the appropriate password;

5. Sacrificed three chickens and a goat (in theory).

=============== ========

Most of the articles I've read say it's simply a permissions problem, like
the error reports. But it doesn't seem that any kind of permission changing
on the resource works. Anything else I should try?

Thanks for any help!

Have you given the IUSR_<MachineNa me> account access to the folder? Had a
similar issue not to long ago, seems that the ASPNet account isn't enough
and wound up having to give access to the folder to the IUSR_<MachineNa me>
account.

[Andrea D'Onofrio [MSFT]]

Have you turned on impersonate in .config file? If yes, your web code run
under the the authenticated user of IIS; then you have configured the
Anonymous access you must add the permission for the account configured in
IIS (IUSR_machinena me is the default on II5). Else if you have configured
the basic or windows integrated, you must add the permission for the
requester user.
I think that add a simple code the write the process identity could help you
to troubleshoot what's happens:
Response.Write( "Identity: " +
System.Security .Principal.Wind owsIdentity.Get Current.Name)

HtH,
Andrea

Thanks for both your replies!

I added the IUSR account to the resource with no luck. I also checked to see
which identity is being used via Response.Write( "Identity: " +
System.Security .Principal.Wind owsIdentity.Get Current.Name + "<br/>")

(clever idea!) and found that it's the ASPNET user. That user has all the
permissions in the world, aside from being an Administrator. I really am
stumped!

What OS are you running? If Win2K3, then I can't help... ;)
