I got assigned to fix a problem left by another developer who just changed jobs, and I'm not having very much luck with it.

The application is a time entry site that allows users to log in with their existing Windows credentials to manage their time. I can pass their username and password in JSON via Postman to the login page and it will authenticate, however, when the same credentials are entered into the form via browser, it fails.

I've posted some screenshots and code behind the login page below. If there's anything else you need to see, just let me know.

What I have tried:

Checked the code and tinkered with setting in IIS manager
