Configure IIS authentication from another domain

Question

Hi I have the following scenario: I have Web Application hosted on IIS and I am in domain abcom. The IIS is configured to authenticate the users with windows authentication and everyone that in the domain abcom can enter the site. But there are users that in another domain lets call it cdcom and they can't enter the site with their windows credentials because the IIS check against abcom...

How can I configure IIS to check for windows user in cdcom? Thanks!

You need to set the identity of the application pool of that website:

1. Open IIS
2. Under "Application Pools" right click on your website's pool, choose "Advanced Settings..."

5. Recycle just in case

You application is now using the user you've configured.
