Unlike Win9x, NT assigns access rights based on a userid/password. The user must log into the machine (or in an NT Server environment, into a domain which acts to provide authentication for the NT box) rather than just supply a password. If the Windows user name on the other workstation doesn't correspond to a valid userid on the NT system, the user will not be able to access any shared resource on the NT system unless they explicitly log into the NT system with a valid userid/password combination.

Also, there is a limit on the number of simultaneous connections under NT Workstation; if you need more than 10 concurrent users accesing resources on the NT box, you'll have to go to NT Server.

This is probably an issue with the protocol stacks on the NT Workstation, and their binding to various NT Services, or the protocols and stacks on the invisible Win9x stations. It's likely that the 'invisible' stations don't have one of the protocol stacks installed on them, or do not have File and Printer Sharing installed; I've seen similar situations where stations withput NetBEUI installed were not visible in the NT Network browser, although they could be accessed by UNC, or were invisible until they shared something to the network explicitly. I've also seen situations where NetBEUI was not bound properly on the NT Workstation.

You're going to have to either learn NT or hire someone who already knows it, because there's quite a bit more to the networking configuration of NT than there is to Win9x. I'd recommend starting with the Microsoft course of study for the Network Essentials and NT Workstation certification tests.
