I wasn’t joking and I found a work around just before Jerry went to
check.

The server has a problem doing a DNS lookup of itself. This causes a
problem for wp-cron execution. When a page loads WordPress tries to
call wp-cron.php, it uses fsockopen and tries to resolve the servers
address. After a 20 sec timeout it fails and continues with the page
building.

The work around:
In wp-cron.php comment out:
if ( $_GET['check'] != wp_hash(’187425′) )
exit;

Manually call wp-cron.php : http://example.com/wp-cron.php
Sometimes you have to do it twice, I don’t know why.

The real solution is to contact the provider and have them setup a DNS
where the server can resolve itself.
