I am trying to make two laptops chat running a mIRC client on each laptop and UnrealIRCD on one of the
laptops as the server. The two laptops are connected via an Ethernet switch with no other connectivity whatsoever.
Both laptops have their wifi disabled. They are completely isolated except to each other via the ethernet connection.
They are running Win 10 and are in a workgroup; they are NOT in a domain. One of the two laptops is also running the
UnrealIRCD server software. Both of the mIRC clients get the following message:"Unable to connect to server (Permission denied)

I have never configured IRC before and I am trying to make this as simple as possible so that I have a "known good" configuration
before I try to get more sophisticated. Any thoughts on what I should look for?
