Turns out sleep was the culprit, though I'm unclear why. Turning off sleep
allowed a full backup to run. I use a wakeonlan script to wake a sleeping
computer for nmblookup and ping and have no problem with other computers. If
sleeping before the backup started, this one would run for 4-6 minutes, then
terminate (sleep was set for 30 minutes). This is a Dell Dimension E520; I use
the same technique on other computers and they complete their backups ok
despite having sleep enabled, but they are different hardware. I'll keep an eye
on this one to see how it goes under normal schedule with and without sleep.
Luckily we are finally getting some new computers soon to move us totally away
from XP, so this one may be retired in the next few months.
Thanks for the help.
