I have a peer-to-peer network with Windows XP Pro pc's and 1 Windows 7 Pro pc. I have shared a folder and have given permission to everyone. Encryption was backed down and passwords were set to be unnecessary. User accounts for the workstations on the Win7 pc were set to unneeded. Connections were made and everything is good to go except the connection is slow. I changed the system to require user and password. Still slow. I installed a new nic. Still slow. What do I do next?
