I have 2 computers networked with a D-Link router. One is running
Windows XP Professional, the other Vista. I'd like to be able to print
to the printer attached to the XP machine from the Vista computer. The
workgroup name on both machines is identical and the printer in question
is shared. The Vista machine can see the XP machine but not access it
(am prompted for a username and password) but the XP machine cannot see
the Vista machine. I've tried the network setup wizard in XP several
times to no avail using various options. Any help with this is greatly
appreciated. Thanks.
