Did you know?
That you can't fully manage an IIS 6 server via Windows XP using the Internet Information Services Manager (the MMC to manage IIS) that ships with Windows XP?
You can resolve that issue by installing the IIS 6.0 Manager for Windows XP.

This is due to an issue with the version of the IIS Namespace for ADSI installed on the Windows XP machine and the updated version of that API that's in Windows 2003 for IIS. I think it's actually a WMI thing...I can't remember, but either way if you download and install the tool you should be all set.
