|FAT32 Windows cannot access NTFS partitions.|
Rubbish! The file system that Windows is installed on has no relevance at all the file systems it can read. A Windows XP installation on Fat32 can read an NTFS partition just as easy as if Windows XP were on NTFS itself. It is the OS that does the reading, not one file system reading another.
Over a network even a Windows 98 installation can read an NTFS partition. The file system has nothing to do with it.
To answer the question with any degrees of accuracy more information is needed. Is this over a network or a dual boot installation. If it is a network, information on the network configuration would help.
What error messages to you get when you try to access . It is probably a permissions problem.
