I have a 2 pc network running XP on 1 computer and ME on
the other.  They are connected through a broadband router
which is connected to a cable modem.  The XP computer can
access the shared files on the ME computer with no
problem.  I can see and access both computers in My
Network Places on XP.
However I can only see the shared XP files from ME.  
Can't access anything.  I keep getting the message:

"\\....\my music is not accessible.  Not logged on"

when I try to access the XP shared music folder.

The biggest frustration to this is that the XP computer
is on and logged on!!  I have restarted this computer
many times and even assigned a password one of the users
to see if that would make a difference to the ME computer.

No difference whatsoever!!
Help!!
