Slow win7 machine on network

[scrossan]

Hello,
Why would 5 of my windows 7 machines be running slow on our school network. I have updated drivers. We also have new laptops which are running windows 7 and access the network wirelessly. These are fine. The Main server is 2008 r2 while the data is stored on a 2003 server. Any tips would be greatly appreciated

Thanks

What is slow exactly? Logon, network file transfer, applications running slow on the PC, what? Have you tried different network ports? What if you swap locations with a slow computer and a fast one?
