I have 2 home computers on a home network. Recently I had to reinstall Windows from scratch on the host computer. After setting up the home network using the wizard I found that the host computer would recognise the guest computer but not the other way round. When trying to view other workgroup computers from the guest I get an error message, you might not have permission to use this network resource, I get the same message when trying to access the guest from the host. The files, folders & printer are configured for sharing. The only thing that can be accessed from both computers is the internet, this proves that the connection has been made.
