SYMPTOMS
When you are using an Olicom token ring network adapter with your Windows 2000-based computer, you may not have full network connectivity to segments of the network, and you may receive one or more of the the following error messages:

Network path not found.

Host unreachable.



CAUSE
This issue can occur if you are not using the most current drivers for your Olicom token ring network adapter. The Olicom token ring network adapter drivers that are included with Windows 2000 do not include the ability to input a locally administered address (LAA). This is required for a flat token ring network to cross some networking devices such as bridge filters and some types of routers.



RESOLUTION
To resolve this issue, contact Olicom to obtain the most current drivers for your Olicom token ring network adapter. For information about how to do so, please view the following Olicom Web site:
