SYMPTOMS

When you use the GetAddressByName API in a sockets application to resolve the name of a service in an IPX network, a SAP broadcast storm may occur.

CAUSE

By default under Windows NT, the GetAddressByName API will contact the NetWare preferred server bindery to resolve the name of the service. If the bindery search for the desired object fails, a SAP broadcast occurs on the net for the desired object. This SAP broadcast can cause a SAP broadcast storm.

RESOLUTION

Use the Updated files.
