DNS Problem TCP / UDP

[William Stacey]

DNS uses tcp for zone transfers. I don't believe you can configure a server
to do xfrs using udp. If your provider has tcp on 53 disabled, their dns is
not configured correctly and should be fixed or change providers. It is a
~simple matter to change dns providers if you want to host a secondary
yourself.

Hello NG,

everytime I want to start a zonetransfer I recieve an error message like
"unable to do a zonetransfer over udp ... use tcp" or something like that.
My Problem is, that my provider uses UDP for zonetransfers. Does anybody
know how to configure my Windows 2003 to do zonetranfers over UDP?

Thanx for help...

Jerome

Or maybe UDP is not open at the entry point.

It might also be possible that my firewall is resposible for that problem. I
have a problem to get my port 53 away from the status "filtered". When I set
the IPSec rule to "open without security" I still get the result "filtered"
is there a scriptlet in VB or something like that, which might set that for
me ... it was easier under Linux :-/

No, it doesn't. ("zone transfer" does not use UDP/IP.) That is,
therefore, _not_ your problem.

No. No-one does.

There must be some other setting stopping it. Disable it and see if it
works. If using IPSec just for filtering, I suggest that it's better off to
have an entry point firewall to take care of the whole network.
