This error message indicates that a DialOut/EZ Site Edition redirector was unable to contact or otherwise obtain a license from the Tactical Software License Manager.Troubleshooting procedure:Verify the license information (License Key, Number of Ports, IP Address) on the License Manager, and that the License Manager shows a non-zero number of licenses at the top (i.e., "0 of 16 licenses").Reboot the License Manager machine. This is often required after the License Manager is first installed and the License Key is entered for the first time. This will often solve problems if the machine is having any other issues.Check that the hostname or IP Address of the machine running License Manager is entered into the DialOut/EZ Site Edition client. This is done from the Licensing button in the client's main interface.Make sure that the PC running the DialOut/EZ Site Edition client can ping the machine running License Manager.If there is a router or firewall between the machine running the DialOut/EZ Site Edition client and the License Manager, make sure that it is configured to pass TCP connections on port 2392.Verify there are available licenses. If the License Manager shows "16 of 16 licenses", for example, there are no more licenses.
