I have small server with IIS and windows server 2008 hosting one page. Sometimes my bandwidth is completely overloaded. How can I check what files are being downloaded from my server that is killing my network connection?
Check your IIS logs. In some instances you will need to have pre-selected the option for logs to be written. If you are watching an actively flooded server, try sysinternals tools available on the web. Specifically "Process Explorer" to monitor what files are being opened and closed by what processes, and "TCP view" to see what addresses are requesting files.
