No one responded, so I've now installed this on the emacs-29 branch,
and I'm closing the bug.

Hello,

I'm trying to connect Emacs client running on Windows over TCP to the Emacs
server running inside WSL.

# Inside WSL shell:
(cat <<EOF
(setq server-host "WSL_IP_ADDRESS_HERE")
(setq server-port 12345)
(setq server-use-tcp t)
(server-start)
EOF
) > server-config.el
emacs -Q -l server-config.el --daemon

# On Windows
# Map network drive \\wsl.localhost\Ubuntu as, e.g. W:
# Then in PowerShell:
$env:EMACS_SERVER_FILE=W:\home\user\.emacs.d\server\server
& 'C:\Program Files\Emacs\emacs-29.1\bin\emacsclientw.exe' -c -n

Client will first display message window saying that it connected to the
remote socket, and after clicking [OK] button, error message appears
saying "*ERROR*: Could not open file: CONOUT$".
