PS C:\WINDOWS\system32> docker start samba
Error response from daemon: driver failed programming external connectivity on endpoint samba (84c73bbaeff98db4708de528cac49e69257e56a9b3e8524c5840815bbe99aa47): Error starting userland proxy: Bind for 0.0.0.0:445: unexpected error Permission denied
There’s a post about this here which identifies the issue but does not suggest a workaround. It appears Docker Desktop is using port 445 for its DockerSmbMount and default MobyLinuxVM. There’s a brief mention of port 445 in the docker for windows guide referencing Shared Drives. I have no shared drives defined, however I do see shared drives at \10.0.75.1.
Is there a workaround for this? What is the recommended solution for allowing access to Linux volumes from my Windows host while the Linux image is running?
I am following the same walk through the instructions given in yocto manuals experiencing the same problems as you have pointed. I was nevertheless able to go a little bit further to get samba container starting. The error I get when starting SMB container is not exactly the same as yours but I guess it is in close connection with it,
Error response from daemon: driver failed programming external connectivity on endpoint samba (1af329bb593fde5634afac49b7f98805309feddcce76f156b711c15fdecbf590): Error starting userland proxy: listen tcp 0.0.0.0:445: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.
netstat -aon | more in cmd prompt tells me a bit more about this error: windows 10 host is already listening to port 445 through PID 4 and there should be only one listener at the same time.
Protocol Local Address Remote Address State PID
TCP 0.0.0.0:445 0.0.0.0:0 LISTENING 4
Looking for the PID in taskmgr confirms it is System.exe process but does not tell very much about it. So I tried to desactivate SMB support in the host. Googling a bit, I have found a good piece of info about Windows file sharing.
that LanmanServer win10 also labelled Server service was delivering SMB support. I opened Windows Management Console and Services, stopped it, and picked disactivated as restart state. I then rebooted my host. The 445 port was no more listened to by the system as easily checked with netstat. I then recreated the SMB container and started it without pain,

A stable process 7080 has been spawned listening to 445 port and this process is named com.docker.backend.exe according to taskmgr. I can not test it on a VM created with Hyper-Virtualization enabled since I can not have this machine and DockerVM up at the same time (due to RAM limitation (4GB for me in total)). I don’t know if SMB host servicing should be restarted after starting samba container. Could you tell me if this is working for you ?
