Problems with TCP/IP networking can be difficult to track down; from experience I can say that I spent countless hours trying to determine root cause of an issue. There are also a variety of troubleshooting tools, which makes this even harder since one has to make a decision on the tool selection when face with such issues. First make sure you have a clear picture of the issue and a good understanding of the tool you are about to use for this purpose.

Many TCP/IP issues are related to incorrect configuration of networking componenets. With respect to this, the netsh Diag context is a really good at helping you discover what is going on. Typing at a dos command prompt will provide usefull information. Also placing a /v at the end of that line will provide additional information. A good resource is a command line book from MS press :http://www.microsoft.com/learning/en/us/Books/6787.aspx
