AXFR from Windows 2008R2 failing after upgrading to 9.18

[Lefteris Tsintjelis]

Error seems to be related to character set checking. I do have the zone 
configured to ignore checking names but it doesn't seem to work.

zone "domain.com" { type secondary; primaries { 1.1.2.2; }; check-names 
ignore; max-journal-size 32k; masterfile-format text; file 
"/usr/local/etc/namedb/secondary/db.domain.com"; };
