port-scanning

I'm trying to install and run the nmap tool to test my server, but it keeps saying

Note: Host seems down. If it is really up, but blocking our ping probes, try -P0

and showing all the server ports are closed. Which is not true - the server is up and has lots of open ports. Any ideas?

UPDATE: Just to clarify - the server can be pinged and port-scanned fine by other programs. It's juts nmap that does not work. Even "google.com" seems to be down for nmap.
