I have a setup with a couple of clients (win2K german) and a linux box running samba (which should act as a PDC). The setup was previously working ok. However after updating the installation something seems to be odd. I still can access all shares (giving valid credentials of course) but the server refuses to act as a domain controller. When adding the clients I get the errormessage: (Translated) Unable to add Computer to the Domain for the following reason: unknown user or wrong password. at the same time the log.smbd file gets two new entries saying: [2002/07/21 16:45:30, 0] rpc_server/srv_samr.c:api_samr_set_userinfo(670) api_samr_set_userinfo: Unable to unmarshall SAMR_Q_SET_USERINFO. [2002/07/21 16:45:30, 0] passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) unable to open passdb database. I looked all over for this problem but I was unable to find a posting anywhere on the net containing a solution. nb. all steps of DIAGNOSIS.txt were successful Anyone an idea? Regards Martin
