Cisco-Win2000 isdn connection

I want to connect cisco 2611 router with Win2000 router through ISDN, but I can't make them to use chap authentication. Is it possible?

Can you get them to connect using PAP as a minimum test - the win2k end supports MS-CHAP by default, you will have to configure it for just CHAP.
