I installed window 2003 server on a VM then i installed the CUCCX. The all process looks fine during the setup. When i log back in i see on the screen CUCCX set up failed close the browser now. I don't know if my missed something during the process.
Did you use Cisco Windows 2003? It won't run on regular 2003 server from my experience. Also, did you perform the registry hack required for VM Ware?
