title: How to quickly connect 2 PC together using Ethernet without router / DNS
body: <p>In the field I often need to perform remote debugging on a target PC using my Delphi development IDE running on my (host) laptop. Because I cannot use any pre-existing network address infrastructure I use a cross-over network cable directly linking the two PC's. I then setup manual IP address of (say) 100.100.100.1 and 100.100.100.2 for the two and after much rebooting and fiddling I get the shared folders that I need. Finally after working in this way I have to carefully put things back to how they were.</p>
  
  <p>This is pain though. There is a lot of typing and room for error. Further, sharing can take a while before things become visible. Is there some way that I can run something (or write a script) that would ease this process in any way?</p>
