Appx/Client timeout duration
What controls the timeout duration, before the Appx/Client gives up on trying to talk to the Appx/Server? The Client itself? The network?
It depends on the message that you see. We don't specify a timeout. We simply request a connection to the host identified by the user.

If the user gives us a host name (as opposed to a numeric IP address), we have to convert that to an IP address, using the TCP/IP stack on the client machine. If the server's name is in the hosts file (/etc/hosts or %WINDIR%\System32\drivers\etc\hosts), the conversion should be nearly instantaneous.

If the server's name is not in the hosts file (or if file-based lookup Has been disabled), the conversion requires a network conversation with a DNS name server - that can take quite a while.

If the name cannot be resolved, you'll get an "Invalid Host Name" error after a while.

If the host is not reachable, the IP protocol specifies some number of retries (and some waiting period in between retries) before the TCP/IP stack gives up and tells Appx that the host is unreachable.
