Sharepoint asks for NTLM credentials for every unique URL. How do I stop it?

ntlm

I'm tasked with troubleshooting a problem we're having with a SP2010 site. The app is external, and there are several clients that must connect. Some clients are receiving a crazy amount of credential requests when trying to log on. It appears to ask for every unique URL (eg. every different picture, link, etc) and it won't stop. Other clients are having no problems.

I cannot seem to replicate the issue, either. I'm attempting to replicate by restricting all settings (including cookies) on my own browser, but to no avail.

I put the HTTP request under a microscope, and it's asking for NTLM credentials.

The client is using IE8, and the browser is running in Protected Mode, but the browser settings cannot be determined...

I'm guessing this is a webserver thing, simply because it appears to be an authentication thing. What might the problem be?
