Enable Source Routing on Token Ring Networks (Windows NT/2000)
Category: Home > Network > Protocols > TCP-IP

Setting this parameter to 1 will force TCP/IP to transmit ARP queries with source routing enabled on Token Ring networks. By default, the stack transmits ARP queries without source routing first and retries with source routing enabled if no reply was received.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'ArpAlwaysSourceRoute' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.


(Default)	REG_SZ	(value not set)
ArpAlwaysSourceRoute	REG_DWORD	0x00000001 (1)


	HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters

Settings:

System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters]
Name: ArpAlwaysSourceRoute
Type: REG_DWORD (DWORD Value)
Value: (0 = false, 1 = true)

Disclaimer: Modifying the registry can cause serious problems that may require you to reinstall your operating system. We cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.
