Setting IP config in Win PE3.1

I have a winPE 3.1 image that loads from CD of PXE.  My desired application, BOINC, runs well.  However now I would like to network 10-20 PE3.1 computers onto a sub-network.  This network will be tied to a XP computer that will store the images and provide interface to the WWW.  In this server I will use ccproxy.

However, I am having trouble setting up the PE to interface with the server ccproxy.

So far the following lines do not work.

netsh int IP set address name="local area connection" static 20.0.0.5 255.255.255.0 20.0.0.1

netsh interface ip set dns name="Local Area Connection" static 216.144.187.199

ipconfig /all

pause

:LOOP
ping www.google.com
goto :LOOP

Using this test, it appears the DNS is not working yet.  ( I have ccproxy set up for DNS and HTTP services)

Any ideas?

Thanks in advance.
