Windows 2003 Deployment script in Windows PE 2.0

Hi,

Does anyone here know what kind of scripting technology is available in
Windows PE 2.0? I am trying to write a script which will do a few very
simple things like:

detect the IP address of the host and if it is in a specific subnet map a
network share to a certain IP, if it is not in a specific subnet use a
different IP (local vs WAN).

Just little things like that, does anyone have any advice for how I can do
something like that inside Win PE 2.0?

thanks,
Drew
