windows-server-2003-r2

Hi, I'm running a Windows 2003 Dedicated server, and the box has been rock solid for more than 2 years now. Just recently, I have had an issue where after a certain ammount of time the server will just stop accepting connections on all ports except 80, and still responds to pings. If you surf to a static HTML page on the box, you can display it. If you pull up a PHP file that has an outside database connection, it fails. RDP refuses to connect, and LogMeIn reports that "The connection was reset"

The only fix at this time is to have the provider physically reboot my box to correct the issue. The event log doesn't seem to be leaving helpful messages, and I am at a lost to what is causing this error since I have not installed any new software in months on it.

Any tips or help would be appreciated to tracking down this issue. I don't mind updating the question as responses come in, I just do not know where to start troubleshooting because it seems random at this time.
