Excuse me for replying to myself. The reason this was not working, as
mentioned by Billy above, is that the first IP listed by ipconfig is not
the IP address I had defined in the autodetect script. Many of the windows
machines I had specified sit on multiple subnets. Thanks for the tip
Billy. I'll have to find another way to get this working.
