Maybe I'm missing something, but I've read or tried to re-read almost every article I can find on PXE redirection but can't seem to figure out how to configure it within my company.

I've got three main office locations (each with multiple VLANs) all connected via WAN. Then I have multiple (up to 50) remote sites across the US that will need to get images deployed. Each of the main sites have full DS servers with PXE servers. The remotes though won't have DS, but some could have PXE if needed. How can I get a machine at a remote site to PXE boot and download an image without pulling everything (pre-boot and image) across the WAN? Does anyone have any setup even close to mine? Would love any insight you can offer.

I'm using DS 6.8 SP2, WinPE 1.6/2005 boot image, XP image.
