On the WinXP PC, create local user account(s), with non-blank
password(s), that have the desired access privileges to the desired

configured properly. Also, make sure that WinXP's built-in firewall is
disabled on the internal LAN connection.
On the Win2K PC, create local user account(s), with non-blank

shares. Log on to the other PCs using those account(s), and you will be
able to access the designated shares, provided your network is
configured properly.
