    Windows 10 using port 445


    I am attempting to setup an SMB server using a third party software, but it says that port 445 is already in use. I ran "netstat -abo" and it says "Can not obtain ownership information". It also reads that a process with id of 4 is listening on it. This process is labeled as 'System' in task manager, so I obviously can't end it. How do I free up this port and use it with a different app? Any help appreciated.

    :)

    SMB without port 445

    I have a samba share, and the network my devices are on blocks communication over port 445 (the standard SMB TCP port). Linux devices and Macs can connect to this device because they can communicate with the server using port 139 (NBT over IP), which is not blocked Windows devices, however, seem to insist they communicate over port 445.

    Is there any way for me to tell Windows 10 to use port 139 without relying on port 445?
