just off the top of my head:

- check if services are running:
service httpd status, ps aux|grep httpd

- check if they are listening
netstat -l

- restart them, restart network:
service httpd restart, service network restart

if there's an error in the operation it will show in
the logs

- check mem space (HD and RAM) and CPU
df, free, top

- see if you can connect locally to services

- revire firewall
iptables -l

- review all relevant logs, not just /var/log/messages
but for example /var/log/secure, /var/log/httpd etc


hope it helps,

Fernando
