Authorization Problem

[Sunny]

Hi all,

I have an ASP.NET application which worked fine on the live site. We
performed a recent upgrade and have a strange problem. When I access the
home page (default.aspx) it pops up an authentication dialog box. I click ok
or cancel 3 times and get the following error:

====
Access to the path "C:\WINNT\Microsoft.NET\Framework\v1.0.3705\Temporary
ASP.NET Files\root\ec99ce5e\f59722f\xifdaakl.0.vb" is denied.
Description: An unhandled exception occurred during compilation using the
CodeDomProvider 'Microsoft.VisualBasic.VBCodeProvider'. Please review the
stack trace for more information about the error and where it originated in
the code.

The ASP.NET process is not authorized to access the requested resource. For
security reasons the default ASP.NET process identity is
'{machinename}\ASPNET', which has limited privileges. Consider granting
access rights to the resource to the ASP.NET process identity.

To grant ASP.NET write access to a file, right-click the file in Explorer,
choose "Properties" and select the Security tab. Click "Add" to add the
"{machinename}\ASPNET" user. Highlight the ASP.NET account, and check the
Write box in the Allow column.

Everything seems to work fine when I browse into mysite/admin (I dont get
any authentication popup over here).
The hosting guys say everything is fine with the security of the ASPNET
user. What could be the problem?


Thanks,
Sunny.

Hi,

You should need full control ACL for the ASPNET account or whaever account
you use in C:\WINNT\Microsoft.NET\Framework\v1.0.3705\Temporary
ASP.NET folder. For more details see:

Regards,
Hernan.

You may also want to check and make sure that the asp.net mappings are
still correct on the machine.

Thanks Hernan & Holly. I asked the hosting provider to re-check their
settings and they got the problem rectified after having said earlier that
their settings were "perfect".
