Subject: [PATCH] [NETSHELL] Improvements to the network setup (1/x)

Step 1: Find the TcpIp transport and enumerate the installed network adapters using INetCfg.

Next Step: Find out how the binding process works and bind the TcpIp transport to all enumerated network adapters. This will replace the blind binding process we are using right now.
