If that is the only output you get I think you will have to contact TAC

Dont know if the 4400's  still are supported and if you have a contract on it?

Maybe TAC has some way of troubleshooting or rebuilding the bootprocess or it will have to be replaced.

Can you tell use what other troubleshooting you have done?  There isn't much information for us to help you.  Is the unit powered up and accessible via console?  Is the ports up on the controller and in the switch?  Can you ping the gateway from the WLC?
