Site Unreachable - Google Webmaster Tools

Hello. In Google Webmaster tools when i click on the diagnostic section nearly 4000 of my URLS are set as unreachable. Under the details section it says 'No Response' If i click on further information it says "Google encountered an error when trying to access this URL. We may have encountered a DNS error or timeout, for instance. Your server may have been down or busy when we tried to access the page." Please see : [login to view URL] No response = The server closed the connection before we could receive a response. I need someone to resolve this problem. I am using Plesk dedicated server and CRE LOADED shopping cart. ** Cost is a big issue!
