You could write your own or use http://code.google.com/p/softenido/wiki/echoserver. I think you can install simple tcp services in windows which will allow you to connect to echo on port 7. Of course you can always use open web servers:

c:\> telnet www.google.com 80

Then type "GET /" and hit enter twice. You should get google's web page.
