The "client" makes a TCP socket connection to the "server". An X11 Display is
a server that accepts connections from clients and draws things on the
screen. You need an "X server" for your Windows box for the "X clients" to
connect to. The easiest way to pull up a full desktop session from the "Linux
Terminal Server" box is to use XDMCP (X display management control protocol)
to ask the remote box to start up clients to connect to your Windows based "X
server".
You<-"X server" on local box<-"X11 protocol"<-"X client" on remote box
It's all a bit backwards to most Windows people.

You can "boot" a native Linux kernel under Windows using VMWare. You may make
a PXE boot floppy that is aware of the pcnet32 chipset, and you *could* run a
virtual machine that netboots from the server itself - but why go through
that pain?
There is a win32 port of User-Mode-Linux but it's really pre-alpha (without
even simple signal support). Unfortunately, this wouldn't buy you much, as
the virtual machine would have no access to any form of graphics hardware as
would be neccesary to run an X server.

This can be really handy in a development/test environment. Our NKS build
environment is based off of network GRUB with boot menu options to auto-build
a dozen odd base machine images (various configurations, different kernels,
with RAID, purely for burnin) as well as Win2k (using a modular DOS boot
floppy to bootstrap from a Samba server).
