I got a ton of these error messages in my watchdog:
fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: No address associated with hostname in /var/www/drupal/includes/common.inc on line 422.
I had to set status = 0 in the system table to be able to access the site administration.

dwwThen your server machine is not configured to properly support either DNS lookups and/or outbound network connections. See the README.txt file for more, and/or #168828: "Unable to fetch any information" on manual check. Not much I can help you with here.
