Terminal Server Client

[firstname lastname <loopgnimiws@gmail.com>]

Hi,

During the trial of connecting to the remote (Windows) desktop.

I used the terminal server client,

Please note: I have succeed in connecting many times before (no need question about the setting and the Windows other side work functionally).

Just sometimes it failed to connect and showed me:  

ERROR: Channel_register
ERROR: getaddrinfo name or service not known

I googled, seems something concerns the avahi,
it suggested to try: 

$ service avahi-daemon stop
bash: service: command not found

I don't know how to proceed further,

Thanks,

Z.
