Hi Dan - It is possible that the connection setting is not set to 'locally installed Nefsis'.You can check that by selecting the circle 'N' in the upper left of the Presence Client and choosing 'Settings'. From there choose 'Connection' on the left side. You can then check the radial dial 'Use locally installed Nefsis' and then enter in the IP info. Your environment has two IP's for the APS. Check with your IT group for the correct IP to use.Or you can login to the portal site at http://idl.nefsis.comYou can also call us at 858.715.0970 or email firstname.lastname@example.org.
