Cannot avoid 'enter network password' dialog box

Hi!

Please help me with this problem. I think this is very strange and it should work now because I have been through many solution of this problem to remove this enter password dialog box, but none of them helped me. I know that you probebly think that the IUSR_.. account probebly don't have access to a file in the project folder. I have checked this and all files has this account. I have also verified that authentication methods in IIS is set to anonymous access.
When I add Administrators group to IUSR_.. then it works but I know it is stupid to do so I want it to work without it. I would appreciate any help on this issue.

I'm currently using
Windows 2000 Advanced Server
Visual Studio .NET
Asp.Net page that I want to access written in CSharp.

Changes that I have made recommended from articles.
machine.config
Processmodel
[System]
Don't know if this is to any help but I add this in case.


Yours sincerely
Andla
