AXFR from Windows 2008R2 failing after upgrading to 9.18

[Lefteris Tsintjelis]

I turned on all logs channels and this is the error I get:

zone domain.com/IN: refresh: unexpected rcode (FORMERR) from primary 
1.1.2.2#53 (source 0.0.0.0#0

tcpdump seems to also agree with the FORMERR

1.1.2.2.domain > secondary.58648: 113 FormErr- 0/0/1 (45)

Lefteris
