Accessing Y2K Pro from Win98 SE

I have a small network with a Y2K Pro and Win98 SE computer. Problem is: When I double click on the Y2k computer in Network Neighbourhood on the Win98 computer, I get a box showing the resource ie: ‘\\Y2K\IPC$’ and ‘Enter Password’. I have tried the Win98 login password and the User password that I added when I created the User (The Win98 Computer). I have shared the Y2K hard drive. I can access the Win98 computer from the Y@K computer. This may be similar to another question Accessing windows2000 Professional dated 3/31/03. I have done everything suggested there. Do I have to re-install Y2K? Any help appreciated.
