I have a 2 PC's and 2 laptops in a workgroup. My PC can access all the others and all the others can access each other. They can see my PC, however every time they try to access my PC as user name and password box comes up. I only have one user with no password set. I have Windows Firewall disabled and SPF v5.6 configured to allow all network traffic. I can see no reason why other PC's cannot access mine. Please help.
