The problem seems to be, as you say, your unfamiliarity with networking 
rather than *any* operating system. The best intro text on TCP/IP IMHO 
is volume I (don't bother with the other volumes, they are more for 
developers) of Doug Comer's "Internetworking with TCP/IP". Highly 
recommended; I have had every edition since the first and it gets 
updated regularly as new standards come out. With a good understanding 
of networking, you can develop your own diagnostic tests for use with 
*any* operating system.
