SYMPTOMS

When you start the Remote Access Server (RAS) service on a multihomed Transmission Control Protocol/Internet Protocol (TCP/IP) computer set up to receive TCP/IP dial-in clients, the following event is written to the System Log: 

Event ID: 20026
Source: RemoteAccess
Type: Error
Description: Remote Access Server Security Failure. A network error has  occurred when you try to establish a session with the security agent on   LANA x. The error code is the data.
where x is the LANA number of your network card.

This error does not cause problems with RAS service.

CAUSE

This problem occurs when the RAS service binds to two network interface cards (NICs) on a multihomed TCP/IP computer, but only one network card is valid. The network card connected to the subnet that you assign RAS clients TCP/IP addresses from, is the network card that should be bound to the RAS service.

RESOLUTION

To prevent the appearance of this event in the System Log, follow these steps:
  1. Run Control Panel and select the Network icon.
  2. Choose Bindings.
  3. In the Show Bindings for:, select Remote Access Server Service.
  4. Select the binding for the TCP/IP protocol and NIC that you are not using for the RAS client, and then select Disable. For example, the binding entry may be:

    Remote Access Server Service -> TCP/IP Protocol -> <Adapter Driver>-> <Network Card>

  5. Choose OK and restart Windows NT.
