I upgraded from SuSE 8.0 running 2.2.3a to SuSE 8.2 running 2.2.7a. I immediately lost the WIN NT4 PDC so the Windows machines we unable to see the Linux machine. I removed and re-added the computer on the PDC. I then rejoined the domain through smbpasswd. This did not resolve the problem. I noticed the MACHINE.SID file no longer existed. Any suggestions would be appreciated. Regards, Mike
