I'm just posting this out of curiosity. I've got a client who has a couple of computers presently running WinXP Home, which he wants to network together. I'm recommending to him that he ditch XP in favor of Win2K professional. He got a second opinion that XP Professional would be preferable to Win2K (and XP Home).
My feeling is that XP has more secretive and "snoopy" code than Win2K, thus my recommendation.
Would anyone care to offer their opinion?
