Blocker For a unknown reason, on one Windows 10 machine, the local socket is denied access to Drive:

This prevents the account creation.
In addtion to the fix, we should log in TRACE the fullServerName when creating the socket.
Update
As we were unable to reproduce this specific error, we've taken several measures to prevent it from happening again:
- Set World access on the socket to avoid permission issues.
- Close listener before stopping the engine, in case a thread doesn't terminate and we have a zombie app, it won't block the socket.
- Add the pid of the running instance to the name of the pipe to avoid reusing a busy pipe.
