asp.net - file upload working in one and not the other help -

I have a web application that has 2 different versions deployed. 1 is a Aspiknet web form version and makes one a Aspiknet MVC Edition

I have dynamically from a directory folder to the target location of a file upload page file.

I have an issue where a user can upload files to ASP.Net web.

The form version is fine but when the user tries to upload the file to MVC version then the user file IoO get permission error.

Here's the kicker: I can upload the same file in both versions. The user is in a remote location but I believe they are still inside the network because they can work on other parts of the application.

Possible signals: An event that says event logs event code: 4005 failed to authenticate the request form. Reason: The supply ticket was invalid.

Why this is happening but what will be your initial idea?

Thanks,

Rod.

Make sure that has been configured to the same using both applications to create first Form authentication cookies can be decrypted by another app
