Offlining Files and Folders

[ATand HMB]

Having no success with this.
Information from Internet site:

"On the Tools menu, click Folder Options.
On the Offline Files tab, make sure that the Enable Offline Files check box
is selected as shown below.
Select Synchronize all offline files before logging off to get a full
synchronization.Select Synchronize all offline files before logging off to
get a full synchronization."

This first part appears to go OK.

Then:
"To make a file or folder available to you offline
After you set up your computer to use offline files, you need to make shared
network files available to you offline.
Open My Computer. (Click Start, and then click My Computer.)
Double-click a network drive to view its contents. If My Computer does not
contain links to any network drives, you need to assign a drive letter to a
shared network resource.
Click the shared network file or folder that you want to make available
offline.
On the File menu, click Make Available Offline. This option appears on the
File menu only after you set up your computer to use offline files as
described above."

I'm having no luck with this. Tried 2 computers, both XP PRO and can't even
get the option to "Make Available Offline".
Help would be appreciated as this is very important to me.

Thanks
