Security problems with XP and Win2K server

Hi ... I didn't know whether to post this on the Win2K or Win XP boards, so I posted on both. I have a Win2k domain controller, and 50 XP/Pro clients. Does anyone know what Win2000 does to the XP clients when a computer is added to the domain as far a security? Does it take over the security already established by the XP OS?

The reason I ask is because since I added my computers to the domain, all of the local users on the workstation have full security on the Documents and Settings folder, and can see eachothers' profiles and documents. I believe the XP machines are all FAT32...do I need to convert them to NTFS? Is there an easy way to do that? Is there any way to get my securities back without doing this?

Also, I'm using roaming profiles and am having trouble with keeping printer connections. I've tried using a VBS script to assign the printer, but it's not working.

Thanks for ANY help you can give! =)

Well I can tell you that you can use FAT32 on the network. The only disadvantages are the same as before... no encryption, less awareness of file access.

The rest of the stuff I'd just have to hack through... maybe someone else here has done something similar. Or if this thread sits for awhile, try the networking forum.
