The message you are seeing when you start heartbeat doesn't make any sense to me either, but it does indicate that it started correctly.
The line:
VIRTCENT01.summitnjhome.com 192.168.1.23
should be:
VIRTCENT01.summitnjhome.com 192.168.1.200
To cause that IP address to be available upon taking control.
