I try to join a debian squeeze box with a debian woody samba pdc. I use samba and winbind on the squeeze box to join with the woody but keeps getting this error when doing net rpc info or net rpc testdomain root at steinerpc1:~# net rpc testjoin cli_rpc_pipe_open_noauth: rpc_pipe_bind for pipe \netlogon failed with error NT_STATUS_UNSUCCESSFUL net_rpc_join_ok: failed to get schannel session key from server woodyserver for domain domain on woody box. Error was NT_STATUS_UNSUCCESSFUL Join to domain 'domain on woody box' is not valid: NT_STATUS_UNSUCCESSFUL joining to another debian squeeze pdc is possible however. i have no log files access at the debian woody box
