Duane,
A couple of questions to try and narrow down if there is a problem with the Conductor or with the network connection to the Conductor:
1. Does your computer have multiple network connections/adapters?
2. After the initial boot up of the Conductor, what is happening with the lights on the MagJack? Specifically I'm wanting to know of it is blinking consistently every x seconds or does it appear to be rebooting every so often.
3. Since it worked last year, I would assume the Conductor is working OK although you can't get the Control Program(CP) to connect to it. Without a network connection to the Conductor, you won't be able to monitor what's happening on the Conductor, be able to sync. the RT clock to you computer, change audio level, or manually play a show. To test if the Conductor is working you could create a short sequence with a limited number of lights and audio for a show and then schedule that show to run multiple times close to you computer time, assuming the Conductor RT clock is still close to your computer time. Now hook up the hardware/lights and audio to the Conductor and see if it plays the show. If the show is scheduled to run everyday at a certain time it should run if the Conductor is really working. IF this works then we know, as Sam mentioned above, that were dealing with the network or configuration issue.
