98 worksta can’t see shares on NT server

I have an NT domain with NT servers and workstions. I recently added an Win 98 laptop to the domain but I can’t see all the my shares on the NT server when using this 98 laptop. I can see most of them but 2 or 3 are not seen when I browse the NT server. When I use an NT workstation pc all is well but when I use the Win 98 one I have this problem. There are no policies on the domain and share permissions are full control for everyone on all shared folders

How can I resolve this problem for the 98 laptop?

Thanks
