Well, you're right about there being something suspicious about the way XP does business. Browsing win98 clients is just slow as sh.... you know. That's even after the registry tweaks that are supposed to fix the browse problem. Secondly, MS crippled XP to allow no more than 5 simo network connections rendering it useless as an impromptu file server. I have XP pro at home, but it is also on the same box as linux rendering it useless to test the file transfer issue. There is an answer somewhere...............and let me know when you find out what it is.
