how to share files between XP home and XP pro?

[peter]

I can share files between XP home PCs.
I added an XP Pro PC with "simple file sharing" (default) option.
Now, I can see the XP pro's shared folders from an XP home PC.
But on the XP pro PC, when I click on XP home's shares, I get a logon prompt
for XPPRO\Guest.
If I turn on the guest account on the XP home machine, then instead of the
logon prompt, I get an error message "the user has not been granted the
requested logon type at this computer".

What do I have to do to allow the XP pro PC to access the shares on the XP
home PCs?

create a user account on the home machine for the user
that wants to access the files.
