Error Message:

Default zone specified was invalid for adapter "name". Verify the value for the Default Zone for the adapter for AppleTalk Routing is valid using the Routing and Remote Access UI.

Explanation:

The default zone name exceeded 32 characters. This will occur only if the zone name was changed by directly accessing the registry instead of by using Network and Dial-up Connections in Control Panel.

User Action:

Change the default zone name so that it is not more than 32 characters.
