SMB (Server Message Block) protocol used for file sharing in NT/2000 , in the NT , SMB runs on NBT (NetBIOS over TCP / IP) , using 137,139 (UDP),[link widoczny dla zalogowanych], 139 (TCP) port. In 2000 ,[link widoczny dla zalogowanych], SMB can run directly on tcp / ip , while there is no extra layer of NBT , the use of TCP 445 port.
When using network share in 2000 , when faced with options 139 or 445 port. Determined in a session with the following ports :
1, if the client is enabled NBT, then the connection time will also visit ports 139 and 445 , if a response from port 445 , then the client sends RST to 139 port, terminate the connection of this port ,[link widoczny dla zalogowanych], then port from the 445 session of the SMB ; but if no port from the 445 responses received from 139 , then a session from the 139 port ; If you do not get any response, then the SMB session failed .
2, if the client is disabled, NBT, he will only from the 445 port connection. Of course,[link widoczny dla zalogowanych], if the server (on the common terminal ) did not port 445 SMB session ,[link widoczny dla zalogowanych], then it will access failed ,[link widoczny dla zalogowanych], so disable the 445 port, on the NT machine to access the shared will fail.
3, if the server is enabled NBT, then port to listen on UDP 137,138 and TCP139, 445. If you disable NBT, then just listen 445 port.
So for 2000 , the share issue to just 139 ports, 445 port the same to complete.
