An alternative solution is to give the sniffing NIC an IP address that no other 
host on the network uses, and a subnet mask of “255.255.255.0”. Leave the 
default gateway field blank for this NIC’s TCP/IP binding. 

This procedure applies only to computers running Windows 2000.

Install the second NIC in the computer.

Start the computer.

Make sure that neither adapter is using DHCP to get its IP address.

Give the adapters valid IP addresses.

Determine which of the two adapters is to be used for sniffing. 

Connect the sniffing adapter with the switch SPAN port.

Connect the second adapter with a normal switch port that is not monitored 
by the SPAN port.

Use the route command to customize the local routing table so that normal 
traffic does not go through the sniffing adapter.

Verify that the sniffing adapter is not registered with DNS and WINS by 
using the PING <local host name> command. This ensures that the local 
name always resolves to the normal traffic card IP address.

If the computer on which you are installing the VoIP Monitor service has two 
NICs before you install the service, follow these steps:

During the VoIP Monitor service installation, enter the normal traffic 
adapter’s IP address when prompted for the machine IP address.

Enter the sniffing adapter’s IP address when prompted for the VoIP Monitor 
Service.

If the computer on which you installed the VoIP Monitor service is upgraded to 
include a second NIC, follow these steps:

Open the registry and access the following key:

HKey Local Machine\Software\Microsoft\WindowsNT\CurrentVersion\Net-
workCards 

Find the newly-inserted card entry.

Copy the value in the ServiceName key.
