Hi,

I have two computers on a local network, a Dell Desktop and a Dell Laptop. From the Laptop I can access the Users/Public folder on the Desktop. From the Desktop, I cannot access the Users/Public folder on the Laptop. A box pops up stating, "Enter Network Password".

There is no network or any other password assigned on either of these computers. I am logged in as the Administrator on both computers.

Any help would be appreciated.
