HUGE Find For Me. Wasted a week trying to solve & thought I&#039d share. I have secure intranet site using NT Challenge/Response and users continually had errors trying to connect to resources on networked drives (files, databases, filesystemobject, etc.). And they had permissions to the networked resources!!! Resources on web server worked just fine. This explains WHY and how to fix/work-around.
