Peer-to-Peer networking problem

[Sondra]

I know this must be an east fix, but I get it to work. I
have two XP machines in the same workgroup. They can see
each other and PC#1 access the shares on PC#2. But PC#2
cannot access PC#1's shares? I get the following error:

Logon Failure: the user has not been granted the
requested logon type at this computer

Any thoughts would be greatly appresiated!

Thanks!
