I setup my computer to boot from two type of windows, W2k Server ad and windows 98. the funny part about this installation is that both windows are store in same c: drive with FAT 32 and it work perfectly. my question is if I wanted to installed Active Directory to W2K Server Ad, would this feature require a NTFS partition to work? and if it does, will there be any problem with my windows 98 FAT 32 in my c: drive?

I'm pretty sure that Active Directory requires an NTFS partition. I don't think your windows 98 would work. You could always partition your hard drive into 2 or 3. 1 small FAT partition for your boot files, 1 NTFS and 1 FAT32.

With both OS in the same C: partition - that C: has to remain fat32 - otherwise not boot to '98. Would be wiser to establish at least have W2K Ad in its own space - especially if requiring it as ntfs... Presuming you have only a single partition on this drive... Perhaps one route: use PM7x or System Commander to create an Extended partition; then subdivide this into at least three logical-drives, and install W2K Ad into the second one. Use the first 'drive' for shared data bewteen '98/W2K = fat32; the second as fat32/ntfs for W2K Ad; the third for ntfs data. This order of 'drives' allows drive letters to be constant for both OS. If you already have an Extended partition then again using the add-in util(s) reconfigure as it above? Once you have established the Extended as above, install a second W2K Ad to the logical-drive prepared for it; you will have a triple-boot ('98/W2K=fat32/W2K=ntfs). Either of the above avoids a 'total' restart to create a more standard/classical dual-boot. (The classic arrangement has each OS in its own partition/logical-drive; a common system (C: active Primary) partition for boot/startup files only. This C: partition has to be a common file format (fat16/fat32). This arrangement also has the appropriate data areas.) The above scenarios would be half-way there - with '98 in C: and W2K elsewhere; W2K boot-files (only) would be in the C: ('98) partition = fat32. One 'minor' advantage of the triple-boot is that with a W2K in C: as fat32, if the ntfs version goes 'belly-up' you can still access ntfs areas from the fat32 W2K Ad...

Yes, AD requires NTFS.

There is a exection file on your server disk for win98 clients. Find it and run the executable on your 98 box. You should be able to use AD then.
