I was wondering what could cause some w2k clients being prompted for pasword
and login again and again ( laptops )

their registry for authentication is 

hklm\system\currentcontrolset\control\LSA is set to 1 ( user NTLMv2 session
security if negotied )

same thing on desktops has no issues.

same users when mapped to samba-2.2.4 has no problems 

samba is in domain mode. ( a account DC is serving client authenticatins )

samba server is member of resource domain.

NO.  Support for NTMv2 is only in HEAD.

This isn't 'negotiated', the client just sends what it likes.  

Samba HEAD has a multiphase generic security negotiation setup using
extended security (SPNEGO), but I'm not about to explain how that works
tonight :-)
