'Hardening' a Remoting Server

[jabailo]

I set up the Remoting Chat application so I could run the server as a
windows service.

This is code I'm using with some .config modifications so I can run it
across a network:

It works great, but occasionally it 'hangs' and the clients cannot
connect to it.

If I restart the server it works great again.

Question: Are there recommended practices for 'hardening' such a server?

Is there a way to ensure that the server is up and in a connectable state?

Should I be wrapping more code around my connect methods so that it can
handle errors, recover better and if so can someone suggest a guideline?

I don't want to be restarting this server every day !!!
