Scenario: 1 desktop, 1 notebook, both running XP Pro sp2. Both in same workgroup. Both can see each other under View workgroup computers. Both can ping each other. Notebook can see about a dozen shared folders on the dewsktop, but can only access one folder. The rest say "access denied". When I try to access the notebook from the desktop, it says "Login failure". I've completely uninstalled antivirus and firewalls on both systems and have activated guest accounts on both. I'm going nuts - any ideas?
