Proberly the best plan reinstalling the whole lot if you feel the urge.
I spent a week resetting windoze printer Q's spoolers after some knob transferred them off a 2.11 bindary novell server with an up time of 2 years!!!
It took me a week to find it on a pre rollout audit. Found at the back of a cleaning closet raw bolted to the wall with zero ventilation and quite happily having 50 odd Q's and 1500 users hanging off a 486. The replacement windows option was 2 servers each costing 10k plus and gawd knows how much in licensing costs.
