Windows Vista Win98/Vista networking

I'm trying to get a windows 98 machine to access shared drives on my new Vista machine on my home network but am having no luck. I got the XP machine to access Vista by creating and ID/pwd the same on Vista and XP. I did the same on Win98 but even with the ID having the same password as it does on Vista, when I click on the Vista machine in Network Neighbourhood, it only asks for a password (doesn't let me enter an ID), and no matter what password I type in for the IDs I have on the Vista machine it says invalid.

Any way to get a win98 machine to access shared drives on a Vista?

 

On the Vista machine this will give you unrestricted access across the network:
Right-click Computer > Manage > Storage > Disk Management then right-click the drive graphic > Properties > Security Tab > Edit > Add then type "˜Everyone’ (not the quotes) and below it select your preferences, e.g. Read or Full Control. Now Apply, OK, etc. to finish.

 

I rtried that but the win98 machine still only gives a popup window asking me for a password and the "ID" it shows it IPC$. How can I get win98 to use the ID/PWD that I created on both machines and login with on win98?
