I have had an running Samba 2.2.0 acting as a PDC for Windows NT 4.0 and W2K clients. After upgrading the Linux-system (SuSE 7.2 to SuSE 8.2) and Samba 2.2.0 to 2.2.7 WindowsNT4.0-clients can't login. "The system can not log you on (C000019B)...". W2K-clients can login! If I remove the NT4.0-machines from the domain and rejoin them, then the machines are recognised, but the user-profiles are inaccessible. What can I do? Harald
