Re: [Handle-info] Stamping out UDP [SEC=UNCLASSIFIED]

This is not your *server* using UDP, but the GenericBatch *client*.  I'm afraid that there is no built-in batch command for restricting UDP resolution.  The Java API makes this easy if you are willing to create your own client or modify Handle code.  

An easier solution to your problem could be to configure your handle clients to automatically talk to the local server, instead of verifying with Global that your server is responsible for your prefix.  This is done using the "resolver_site" and "local_nas" files, as detailed in the Handle Technical Manual.
