The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
  • Microsoft Windows NT Server versions 3.5, 3.51, and 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.
