I've tried resetting the Winsock and TCP/IP stacks using netsh.
The XP machine became visible for awhile in the Vista Network folder, but I
could still not access its resources. But then the Vista maching became
invisible to the XP machine.
Now its back to normal (XP can now see the Vista machine, but Vista cannot
see XP)
All I can say now is WTF!?!
Any help is appreciated.
