Hi everybody I have the following problem: I like to run Samba as PDC on a SGI Failsafe system. To test this out at first, I have the following configuration: Samba PDC 2.2.5 on a SGI IRIX system Server Samba PDC 2.2.5 on a PC Suse Linux system Server Win NT 4 Client Always there is only one PDC running. They are configured for the same domain settings. I configure my NT Client for the first PDC as a Domain Client. Then I look out, start the computer again. During this time I shut down the first PDC, and start the second. If I like to log in into NT again, I always get a mistake message. (c00019b) But if I do the change during I?m logged in the NT session, there is no problem. For example when I open a file from the shared disk when the first PDC is up, I can change to the second PDC and save this file correctly Thats my problem Does anyone know how to configre my sytem ? Would make me happy. (;-> Markus
