Impossibile risolvere il nome wpad
Se non si riesce a risolvere il nome wpad, ed il server DNS è Windows 2000 Server, verificare che ci sia l'errore:
EventID 6268 The global query block list is a feature that prevents attacks on your network by blocking DNS queries for specific host names. This feature has caused the DNS server to fail a query with error code NAME ERROR for wpad.rvmgroup.local. even though data for this DNS name exists in the DNS database. Other queries in all locally authoritative zones for other names that begin with labels in the block list will also fail, but no event will be logged when further queries are blocked until the DNS server service on this computer is restarted. See product documentation for information about this feature and instructions on how to configure it. Below is the current global query block list (this list may be truncated in this event if it is too long): wpad isatap.
