FLEXlm error -15 on notebook computer with a port replicator

Error Message

Running a local license manager on a laptop that also has a port replicator, may result in a -15

"Cannot connect to license manager", or similar error message relating to the resolution of the hostname.

Cause

The laptop may be using its built-in network interface card (NIC) to connect to the network, and to connect to the port replicator when docked. The laptop's hostname may be associated with two different IP addresses. This can cause the license manager to crash unexpectedly or fail to connect.

Solution or Workaround

1. Start the Desktop Administrator from Start > Programs > ArcGIS > Desktop Administrator.
2. Click License Manager, located in the left pane.
3. Click Change, located in the right pane, and type 127.0.0.1 as the license manager.
4. Reboot the machine to restart the license manager.
