Anybody find a nice slick way of getting the PROXYADDR variable available in third-party imaging (custom WinPE environment) through PXE? I am trying to prevent having a server list, that I constantly update, for our remote locations.

We do all imaging through PXE/TFTP, but we utilize a very customized version of WinPE. I am now trying to come up with a script that we can use, but if someone else has one already developed, I'd love to "borrow" it!
