I have a Windows XP Professional workstation joined to a SBS 2008 domain. Recently, network activity has become unbearably slow. It literally will take almost a minute to copy a 2 MB file across the network to the server. No other workstations on the network are experiencing this problem. I have updated the NIC driver to the latest version and checked the Event Viewer for any network-related errors. Everything appears to be functioning normally. Also, Internet downloading speeds are normal. The problem appears to be isolated to local network file copying functions.
