I had the same problem two weeks ago, and I changed the default security
level of XP in order to make a workstation join the network (I tried
several times with this workstation). It was very weird to me as a few
day before this problem I connected another workstation without any
problem (and I didn't changed the version of samba between two joins).

Just for the reminder my wireshark patch is dissecting NTLM 1 & 2
version so it might helps.
