samba - Aug 2003 - problems accessing samba-share with win xp (pro of course)

hi all, 

we need to access a debian 3 /samba 3 beta 2 share from w2k-clients and
xp-clients. my "normal" workstation is working under w2k, if i try to
connect the share it works fine, no matter if i use my own workstation or a
workstation running win xp.
if someone who has a xp-machine as normal workstation tries to connect, the
connetion to the samba-share is refused, no matter, if he tries from his
xp-machine or my w2k-machine.
googeling for that problem i found that xp uses another way to encrypt
password, but this should be fixed since samba 2.2.x. 

any ideas??

thanks in advance
