Q198888: Telnet and Browsing to Systems Outside the WLBS Cluster Fail

The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
- Microsoft Windows NT Load Balancing Service 1.0

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.
