So clearly that is a nonpublic domain avi-cenna.local, so ask because it is so common its not funny. Is your exchange server even pointing to your AD dns?
All MEMBERS of a domain need to point to ONLY AD DNS! Your AD dns then either queries directly to ROOTS for non AD domains, or domains he is not authoritative for or he forwards the request to some other server that can do the recursive lookup for said domain. Say your ISP dns, some other caching server on your network that queries your ISP, or googledns, opendns, etc.
Members of domain should ONLY point to AD DNS, having other servers in the list can cause problems. Example your AD dns is 192.168.1.100, so something like
is not right.
