Short answer: cannot be done. You can access shared folders in the Win98 computer from Windows 7 but not the other way around. Scan on one, transfer files afterwards using the other. You can't use a Windows 7 Homegroup to connect this way, you need to use basic file and printer sharing (as in workgroups). Create one account on the Windows 98 computer that has the same username and password as an account on the Windows 7 computer. Set up file sharing as normal on the Windows 98 computer and assign it to the same workgroup name as the Windows 7 computer is using. It should then appear in Windows 7 Network and allow you to access the shared Win98 folders. You may see the Windows 7 computer from Windows 98 but you won't be able to access it.
All confirmed as true, but - WHY??
Windows 7 keeps shoving HOMEGROUP in my face, as if every computer on the planet runs it.
It's notion of a network is corrupt. The whole idea of a network is to share resources.
After days of fiddling where it inserted -PC after the name I gave it, first used HOME as my location, then lost it, created a HOMEGROUP for it, when I never requseted it. Or just simply misbehaved BADLY.
I was finally able to get the windows 7 computer into the same workgroup as my other computers.
It STILL shows it as connetion: internet !! Silly ____..
And now when I try to access it no longer displays an error, but asks for a password.
My normal response to this is (Hit Enter Key - i.e. "none" on well behaved systems.)
I wonder what Windows 7 defaulted to?
No matter, the machine and the OS are going back to the store.
