Hi All I have been trying to join a W2K workstion to a samba 2.2.x PDC for weeks now.I was getting all sorts of error messages and internal errors too. I then remembered something about Redhat 7.0 gcc beeing unstable. I switched to kgcc(included in RH 7.0 also) and suddenly it was possible to join the samba PDC domain!! Conclusion: Do not use gcc in RH 7.0! Use kgcc instead. Jocke
