LOoking at a network trace fomr a working machine it appears that the FIler wants to use CIFS over port 139 as opposed to port 445. Ms CIFS initially tries port 139 but preferes 445. When you disabled NetBIOS over TCP cleint side, it stops attempting to use port 139 and hence breaks comms with my filer. Anyway to get the filer to use 445? </P></BODY></HTML> Thu, 05 Jun 2025 06:22:37 GMT https://community.netapp.com/t5/Network-and-Storage-Protocols/Windows-XP-Client-CIFS-ports-used/m-p/71157#M6490 darraghos 2025-06-05T06:22:37Z Re: Windows XP Client - CIFS ports used https://community.netapp.com/t5/Network-and-Storage-Protocols/Windows-XP-Client-CIFS-ports-used/m-p/71162#M6491 <HTML><HEAD></HEAD><BODY><P>To answer my own question, the config is as follows:</P><P></P><UL><LI><STRONG style="color: #1f497d; font-size: 9pt; font-family: 'Comic Sans MS';">options cifs.netbios_over_tcp.enable </STRONG></LI></UL></BODY></HTML> Wed, 01 Aug 2012 10:25:02 GMT https://community.netapp.com/t5/Network-and-Storage-Protocols/Windows-XP-Client-CIFS-ports-used/m-p/71162#M6491 darraghos 2012-08-01T10:25:02Z
