IIS 4.0 Requires Username and Password When Using a Remote Computer (222069)

We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SUMMARY

When you use Internet Information Server (IIS) 4.0, you can put content on a remote Windows NT computer and access it through an IIS virtual directory. When doing this, you must enter a username and password on the "Connect As..." button.

This is required because Windows NT 4.0 supports only one set of credentials (user information) across an authenticated connection and all connections between two Windows NT computers are authenticated and secure. When you set this option, you must instruct IIS as to what username and password to use.

Note that all access to the computer sharing the network resources is done in the context of the person specified in the "Connect As.." dialog box. Therefore, this account must be both accessible on the remote computer, and have NTFS permissions to the content shared on the remote computer.
