Event ID
14119
Event Message
An external interface could not be found for packet filtering. For more information about this event, see ISA Server Help.
Explanation
This event can occur if the Local Address Table (LAT) includes all the addresses associated with the external interfaces. The event might also occur if another application is controlling the packet filter driver. Since only one application can control the packet filter driver at a time, the Firewall service cannot filter packets.
User Action
Verify that the LAT is configured properly and no other applications are configured to use packet filtering on the external network interfaces of the ISA Server. To do this, in the ISA Management console tree, click Servers and Arrays, click Name, click Network Configuration, and then click Local Address Table.
