Hi,
I have found them.
Configuration file in Windows: “C:\ProgramData\Docker\Containers<GUID of container>\config.json” és “C:\ProgramData\Docker\Containers<GUID of container>\hostconfig.json“
Notice:
Please make a copy from the configuration files. That could be usefull when yor container does not want to start adfter a Docker host restart. When you meet this message: “Win32 API call returned error r1=2147942452 err=You were not connected because a duplicate name exists on the network. If joining a domain, go to System in Control Panel to change the computer name and try again.” you merely need to overwrite the cinfig files from backup then your container will start correctly.
