Have Vista Ultimate installed on desktop #1 and can read/share all the files
that are on desktop #2 which is running XP Pro. However, cannot read any
files that are on the Vista machine from the XP Pro machine. Have tried
everything I can think of with no luck. Any suggestions. File sharing,
etc. are all turned on properly.
