No Single-Route Broadcast on Token Ring with Windows 95 TCP/IP (153749)


The information in this article applies to:

  • Microsoft Windows 95
This article was previously published under Q153749

SYMPTOMS

When you are using a Token Ring network with Windows 95, ARP resolves addresses by first performing a local broadcast and then an All-Routes broadcast, but it does not perform a Single-Route broadcast.

CAUSE

The TCP/IP transport protocol included with Windows 95 uses this method of address resolution to prevent any problems that may occur with older routing bridges.

RESOLUTION

STATUS

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.

MORE INFORMATION

TCP/IP resolves IP addresses to node (MAC) addresses using the ARP protocol. The All-Routes broadcasts by the ARP protocol do not take advantage of intelligent source-routing bridges that can route broadcasts through the single best route and avoid redundant network traffic.

With this update, a Single-Route broadcast is made instead of an All- Routes broadcast if the following registry string value is present and set to a value of "1":

HKLM\System\CurrentControlSet\Services\VxD\MSTCP\ArpTRSingleRoute
