Yep, I was referring to NT 3.51 !! I reckon it was just about sorted and stable with SP6a.
Ran that on a server at home for a few years - no great complaints. Was also very happy with 98SE on a laptop for several years.
I am now a total Win 2K Pro convert - extremely stable, with good inherent intelligence such as plug & play that truly works !
No knowledge of XP and I wouldn't go near ME as I understand that it's a dead end in terms of upgrade paths.
