SYMPTOMS
========

When you use InocuLAN on a Microsoft Windows NT network, you may experience
large amounts of WINS name queries and broadcast storms. If you use Microsoft
Network Monitor, you may view a large number of WINS queries for workgroup or
domain names, and then broadcasts after the WINS queries are unsuccessful.

CAUSE
=====

By default, InocuLAN is configured to automatically discover Windows NT domains.
The default values for Auto Discovery and Heartbeat Update Interval are 24 hours
and 1 minute, respectively.

If a domain is manually entered and/or automatically discovered in Service
Manager, and then later becomes unavailable or invalid, you can receive three NS
Queries every 60 seconds for each invalid domain.

RESOLUTION
==========

To resolve this problem, remove the invalid workgroup or domain names from
InocuLAN's Service Manager. To do this, perform the following steps:

1. In Service Manager, click Broadcast Configuration from the Service menu.

2. In the Broadcast Configuration box, click the NT Domains tab.

3. Remove the invalid workgroup or domain names.

STATUS
======

This problem occurs when you use Microsoft Windows NT version 4.0 and InocuLAN.
