recursive query use tcp ?

[Sukmoon Lee]

Hello.

My Test DNS is not response for "*.tk".
I looked around then my server not work connect using udp for tk's tld name sever.
But this server is work to using TCP. (below test)

If there is an option on the named server that recursive queries use tcp?
I can't search BIND ARM. 

Thanks in Advance.


Regards,
