Just in case you are vigorously refreshing this page, I'll give you a quick and dirty explanation, then I will actually research to see if 98se (btw upgrade your computer) actually is incompatible or what-not.

When you are all on the same network, you may not be on the same 'workgroup' which is windoze' home network (if you ever worked at an office, you probably used a 'domain', or at school, they have domains).

All pcs have to be on the same workgroup to see each other. By default I think the workgroup is 'mshome' but double check that. If other pcs are on the same workgroup but not yours, it may be the issue of your operating system (98se), because a while back I tried to get windows server 2003 to see the XP workgroup, and it kept failing miserably.

My friend told me all sorts of technical mumble jumble about the cause of this, but the long and short of it was 'get a new OS because it's easier to fix one pc than to install server2k3 (or 98se) on every other pc'.

And now to check if I am correct....

edit: apparently you need to have some username setup going on in all of the networked pcs. A link:
