make sure your hosts file is right,eg 10.1.1.1 serverdomain.ping the server make sure the network is working.

It's possible that your firewall is blocking it, also double check your credentials within the cmc are correct and that there is connectivity between your database and your server. Also try connecting through the Administrative account.
