Use this and it won't slip any more- rotafix https://204.73.203.34/fisso/eng/schpignone.htm
I would still use the lock ring as well.

you grease the threads on the cog and lockring first?
rotafix or a good chainwhip/lockring should be fine (seriously, i'm in love with the shimano track tool). hunker down on it with all your (or his) weight

Also, double check the hub threads. Is it slipping while backpedalling/accellerating a half turn or so? Or is it slipping-slipping as in if you pedal hard, it slips forward every time?

i've had a problem with this, which seems simple but it didn't initially occur to me...
my cog was slipping a little, when i pedal hard forward, it would slip, then "lock" against the hub. when i would slow down/skid, it would slip backwards, and "lock" against the lockring. obviously i was like "well **** i need to tighten it down" so when i got home, i tried to tighten down the cog and lockring, but everything seemed snug. next day, same problem. then it occurred to me what was going on. i was coming to a stop before getting off my bike (duh) and in doing so, locking my cog against my lockring. neither wanted to budge under the force of my tools. so i got on the bike, took a good hard pedal forward (anticipating a slip). cog slips forward. got off the bike, then tightened the lockring. haven't had a problem since then.
don't underestimate the power of your legs over your arms!
