Hi,
The error you are getting leads me to believe that you are creating a MAILBOX object instead of a NETWORK object. Can you double check that you are calling
Code:
viz.add(viz.NETWORK,targetmachine)
and not
Code:
viz.addmail(targetmachine)
About the other errors, are you getting them in your networking script or a different one? Are these errors caused when you use a specific function or feature? Thanks for reporting these errors to us.
