I found the solution, which I posted about earlier.  There are AUTOEXEC.NT
and CONFIG.NT in the system32 directory that are used when DOS apps are run
and if you upgrade, your AUTOEXEC.BAT and CONFIG.SYS settings get put in
there.  I was rebooting because I changed AUTOEXEC.BAT since I thought some
of the environment variables were getting set from there on boot.  But I
guess XP (NT and 2K also?) dont' even use AUTOEXEC.BAT or CONFIG.SYS and
just use AUTOEXEC.NT and CONFIG.NT...
