WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
With Windows NT on a Token Ring network, the Source Routing bit can be modified to support bridging hardware that cannot forward frames with routing information. To configure Windows NT so that only half of the NetBEUI frames (NBF) include source routing information when they query a remote server, use the following procedure.
Use the Registry Editor (REGEDT32.EXE) to change the value for QueryWithoutSourceRouting.
To modify the QueryWithoutSourceRouting value, use the following path in the Registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NBF\Parameters
Change the value for QueryWithoutSourceRouting to 1.
Source Routing is offered in Token Ring networks only and allows NetBEUI to be routed. Source Routing occurs when NetBEUI broadcasts a name query frame on a local token ring; if it doesn't receive a response in a set period of time, it enables Source Routing fields in the token ring frame that will cause Source Routing Bridges to recognize the frame. The Source Routing Bridges add additional routing information to the frame and send it to all the other rings. When the frame reaches the desired host, the host will use the routing information added to reply directly to the originating node. The originating node then caches the routing information returned by the remote host to address subsequent frames sent to the remote hosts.
