I have fixed this problem with the same solution for Adobe 

But it’s really strange 
 on x86 it works (after disabling EDNS)

and on x64 it fails(query failed (SERVFAIL))


Fixed with this linees:


// pmk-kunststofftechnik.at servers that don't understand edns options

      server     { request-sit no; };

      server    { request-sit no; };

      server     { request-sit no; };


Best regards

Oggetto: Question abount edns


Good morning,


I have 2 server DNS:

-    BIND 9.10.0-P2-x86 in a Windows Server 32 bit

-    BIND 9.10.0-P2-x64 in a Windows Server 64 bit


I have a problem with a query MX for domain pmk-kunststofftechnik.at


On server Windows 32 bit with BIND 9.10.0-P2-x86 it ok

30-giu-2014 edns-disabled: info: success resolving
'pmk-kunststofftechnik.at/MX' (in 'pmk-kunststofftechnik.at'?) after
disabling EDNS


On server Windows 64 bit with BIND 9.10.0-P2-x64 it’s not ok 

30-giu-2014 12:12:23.190 query-errors: debug 1: client 77.xxx.xxx.xxx#63216
(pmk-kunststofftechnik.at): query failed (SERVFAIL) for
pmk-kunststofftechnik.at/IN/MX at ..\query.c:7532


Do you have any suggestion?


Thanks in advance and best regards
