SYMPTOMS
When you telnet to or browse a system outside the Windows NT Load Balancing Service (WLBS) cluster from a WLBS cluster host, you do not receive a response, but you can ping the outside system.



CAUSE
The TCP/IP configuration is incorrect on the WLBS cluster host



RESOLUTION
If you are using a single network interface card (NIC), the dedicated IP address must be entered before the cluster IP address or addresses in the TCP/IP configuration within the Windows NT Network dialog box. Otherwise, the cluster IP address may be selected as the source address, and the outside system will respond to the cluster IP address instead of to the dedicated IP address. In this case, responses will be directed only to the default host.

NOTE: You will not observe this problem on the default host.

Check the TCP/IP configuration to make sure that the dedicated IP address is first in the list.

You can also use multiple NICs to avoid this problem.
