SUMMARY
If you configure two identical network cards (for example, 3Com EtherLink II/TP cards) on a server and try to run NetBEUI and XNS on each, starting the workstation service results in a SYS0052 error message: a duplicate name exists on the network. Bind one protocol on each card to resolve the conflict.



MORE INFORMATION
The error is expected behavior. When the second card attempts to register its NetBIOS names, they conflict with the names registered on the first card. Under NetBIOS, each card in a logical network must be registered with a unique name.

NetBEUI and XNS represent different logical networks, and you cannot bind the same protocol to two cards attached to the same physical network or to networks that are bridged together.

Bind one protocol to each card (for example, XNS on the first, and NetBEUI on the second) to resolve the conflict.
