"Extended Properties" and "Alternate Data Streams" Incompatible with Offline Files???

On my XP laptop I have a drive letter that is mapped to a share on NTFS
drive on a Windows 2000 machine using Windows Networking (peer to peer) and
has Offline Files enabled.

If I create a text file on my laptop's C: drive, then right click on the
file in Explorer and select Properties, I get a property sheet with 3 tabs:
General, Security, and Summary. And, values that I set for items on the
Summary tab (Title, Subject, Author, etc.) are preserved for viewing at any
subsequent time.

But if I create a text file on my M: drive (which is mapped to a share on a
NTFS drive on my Win 2000 desktop machine with Offline Files enabled), then
right click on that file in Explorer and select Properties, I get a property
sheet with *ONLY* the General tab. The Security and Summar tabs are
missing.

Similarly, I am able to successfully create files with alternate data
streams on my C: drive, but if I attempt to create alternate data streams on
my mapped M: drive, I am unable to do so.

Since both the machines are using NTFS drives, I thought that extended
properties and alternate data streams should be supported on the mapped
drive, but that appears not to be the case. Is there some limitation when
using Offline Files that doesn't support extended properties and alternate
data streams???
