why the WINDOWS DNS servers return SERVFAIL for invalid requests.
fidc1 - 172.25.220.30
fidc2 - 172.25.220.32

These are Windows domain controllers.

When I attempt to do a lookup from a Unix host using those boxes, of something that doesn't exist I get back :

[root@fitmpindexc1r1 root]# nslookup thing
Server: 172.25.220.30
Address: 172.25.220.30#53

** server can't find thing: SERVFAIL

It tells me that the server has failed. Not that the entry doesn't exist.
