I have a little domestic wireless LAN with 2 PC:

..Windows XP SP2
..Windows 2000 SP4

There is no Domain, the 2 PC have the same workgroup name and both PC
have Guest user activated.

Both PC have a shared folder with "Everyone" permission activated.

If I try to connect from Win XP machine to Win 2000 machine it's all
OK.

If I try to connect from Win 2000 to Win XP machine, every time
username and password has been requested.

How can I set-up Win XP SP2 to permit anonymous access without username
and password request (like Win 2000)?

Excuse me, but I'm a novice to networking... :->
