I have a Samba server (Ubuntu 10.04 LTS) with authenticated via AD. Sometimes i have a problem, when a client on WinXP tries to open a file on a share( for example *.xls)Windows Explorer will then freeze up for several minutes and over time application (Microsoft Excel2003) send a message:"server is unavailable". Another user can not open this file, but it can open another file. In samba.log : send_file_readX: sendfile failed for file test.xls (Broken pipe). Terminating.
smb ports = 139;
hard to say what the problem is here. Not a generic known problem. For now I'll close the bug but ff this problem still pops up with the latest Samba release, please try to reproduce this and make a network sniff and level 10 log files of the client that has the problem.
