Net.exe Duplicate Name Error 52 with Multihomed Computer

ID: Q170808

The information in this article applies to:

Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
Microsoft Windows NT Server versions 3.5, 3.51, 4.0
Microsoft Windows for Workgroups version 3.11
Microsoft Windows 95

SYMPTOMS

When you use the Net View command to view any computer from a multihomed computer, the following error 52 message is returned:

A duplicate name detected on the network.

Also, Netstat -n shows the multihomed computer's own computer name in conflict.

CAUSE

This problem may be caused by the following WINS configuration:

Each NIC in the multihomed computer points to a different primary WINS server. Each WINS server thinks it is the owner for that computer's record and is not registering the client correctly as a multihomed host.

RESOLUTION

Disable WINS in one of the NICs, or set up both NICs to point to the same WINS server.
