hi ... i've been trying to make a pdc using samba 2.2.1a in my lab which have 2 kind of NT workstation, one with SP4 the other with SP6. when i try to login to my SP6 clients, i got kick out right after i login without any error/messages from windows. but the same setting works fine with my SP clients. can anyone tell me how to fix this without having to downgrade to SP4 ?? thanks
