I wonder what that does to the security posture of Windows 7.  Though, 
chances are good that's not as big a concern for a hobbyist.  (Assuming 
that they are more responsible about keeping other things up to date 
than the average person.)

It's been too long.  Is the AD Extension strictly necessary on Windows 
98?  I thought that was to allow 98 to brows DFS and as such wasn't 
strictly needed to use old classic \\server\share UNC format.

ACK  I expect that it's standard SMB networking (woes).

I wonder if this is an issue with Windows 98 not doing something, or an 
issue with Windows 7 not sending out broadcasts.

This sounds like classic SMB browse master related issues.  (I wonder if 
WINS server might help.)

Oh God, the bad old days of SMB.

Follow up question.  -  What protocol did you use?  TCP/IP?  I assume 
that Windows 7 doesn't have NetBEUI.  (I've not looked and I know 
Microsoft was trying to deprecate it.)

Thank you for sharing Marc.  :-)
