protecting Share folder

I have network of pc's with mix win95,98,me(workgroup).I had share folders with password protection. Well we have added a new pc with XP Pro. It is formated in NTFS. I have network it, they all can see each others. Problem is security of share folders on XP machine. I have disable simple networking. I know we have to use premissions. But how do windows 98,win-ME, would log on, where and how to create a group for them?
