Incorrect Node Address In IPX Header Causes Broadcast Storm (149448)
The information in this article applies to:
This article was previously published under Q149448 SYMPTOMS
When you use the IPX/SPX-compatible network protocol (Nwlink.vxd) on
Windows 95-based computers on a network with IPX routing, network traffic
may intermittently increase dramatically, severely degrading network
performance. This condition is known as a broadcast storm.
CAUSE
When you start a Windows 95-based computer that uses the IPX/SPX-
compatible network protocol, frames may be sent out with incorrect IPX
header information under certain circumstances. Specifically, the node
(MAC) address is incorrect. Novell NetWare servers and IPX routers try to
respond to these frames by sending to the incorrect address. Because there
is no response, the servers and routers continue to retry, eventually
generating a broadcast storm.
This problem is especially noticeable if the IPX frame type is set to
Auto. In this case, the initial RIP and SAP packets that are sent out to
detect which frame type is in use on the network cause numerous responses
to be sent to the incorrect MAC address. The effect is less dramatic if
the IPX frame type is set to a specific type.
RESOLUTIONSTATUS
This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
