I have a Window 7 machine that is accessing the files on the server very slowly. I have re-installed the client OS, but it seems to be an issue with the server itself. If I restart the server, the problem seems to go away for a while, but then returns. I have two XP machines and a Vista machine accessing the files on the same server with no issues. This problem seemed to coincide with the removal of Symantac Endpoint Protection from the server.
