Why do you think you have a port conlict caused by Docker Desktop? Can you share the error message? I don’t think Docker Desktop would use any port. It uses sockets and pipes in case of Windows containers. It uses ports when you forward a port to a container.
By the way I never understood why so many users try to install Docker Desktop on a Windows server. I also never tried on a Windows server to see how it is different compared to Windows 11, but it is not officially supported to install Docker Desktop on a Windows Server as Docker Desktop is for development.
If you want Linux containers on a Windos server, you can run a virtual machine and install Docker in the VM or folllow Microsoft’s guide to use Windows containers on Windows including Windows Server
No problem. I don’t know about any port that Docker Desktop would use, but you can try running the following powershell command as Administrator:
It will show the used ports and the process id of the owning process in the last column. Then you can find the process name in the task manager, but I am sure there is a power shell command that can do that too.
