Not all Network Shares showing on Win98

I recently install a Win98(2ndEdition) box on my WinNT4 Network. When I check Network Neighborhood, I see all of the computers on the network. But when I open up the ‘Server Computer’, not all of the ‘Shares’ are listed. There are about 12 ‘Shares’ total, but 3 shares (of course the most important) are missings. I can’t figure out any other way to ‘map’ a drive to the missing shares..
