Sharing harddrive.

I am runing a network in a caf? with some PCs runing WinMe 1st edition as a requirement of the timing software we are using. I partitioned all to a ratio of 30:70%, the problem I am having is sharing the harddrive one of the computers, I can’t even see the properties of both partitions because they disappear as soon as they appear, I can’t also go in to MSDOS because it is also disappearing.
