ARS and the Network Interface Card

An Address Resolution Service (ARS) binds to a network interface card (NIC). Only one ARS can run on a host workstation.

Certain circumstances may require that your host workstation have more than one NIC. This might be the case if you are using third-party failover software. In such instances, it is necessary to add a registry entry so that when the ARS starts up it binds to the same NIC each time. This ensures that the ARS maintains the same IP address.

The registry entry is:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Visual Systems, Inc.\CygNet\Net String Value Name: Address Value: the desired TCP/IP address (for example, 192.168.1.5)
