Update to my problem: When trying to network a Win2K Pro PC to the XP Pro's, I did get a network login password prompt for 1 of my XP PC's and vise versa. Why not the other XP PC?? Why Win2K to XP login prompts only, and not XP to XP???

Both XP Pc's are now in different workgroups
The Win2K PC is in the workgroup that didn't get the login prompt from one XP PC

The mystery deepens!

Any suggestions?
