To further explain the above reply, since you cannot "see" the NTFS partition in WinME, it is not possible to share it on the network from within WinME. Because of this, you would not be able to share that partition over the network. However, even if your main Win2k partition is in NTFS, it is still possible for Win2k to see any and all FAT/FAT32 partitions on your hard drives.
Also, I believe if you're in Win2k and have the NTFS partition shared for the network, then you should have no problem getting to it through the network, so long as you set Win2k up to share files properly (either make an account on your Win2k computer that has the same username/password as on the computer you want to access the files from, or enable the guest account in Win2k).
