Hello: A script I use runs smbclient every five minutes to download files from an NT box across an ISDN link. Intermittently (once or twice a day), smbclient fails to connect, giving this error message : " tree connect failed: ERRDOS - 71 " The debug messages seem to show that the session setup is ok, but the "tree connection" fails. Does anyone have any clues on how this can be resolved? Regards, Sonam Chauhan
