Howdy all,
We're trying to setup Dynamic DNS in our environment. Eventually we
will be using Windows DCs as our DNS servers and Linux servers as our
DHCP servers. Right now, the Linux servers are both.
The problem we're experiencing is that on a network capture of the
traffic coming out of Windows clients, we don't even see the DNS update
packets coming out of the machine. From what I've read the process for
Windows 2k/XP clients is:
(1) Send out DHCPDiscover
(2) Get back offer
(3) Send out request
(4) Get back ACK
then:
(5) Try to send out DNS updates to DNS servers
#5 is the part we're not seeing.
We've done all the basic stuff (enable "Register blahblah with DNS"
under the Advanced TCP/IP Properties) as well as registry hacking in
HKLM/System/.../Services/Tcpip/Parameters to make absolutely sure
nothing was blocking us, like adding keys:
DoNotUseGroupPolicyForDisableDynamicUpdate = 1
DisableDynamicUpdate = 0
on both a general and a interface/adapter basis.
I feel that something simple is definitely going on here, but I have no
idea what and would appreciate any ideas. Thank you very much for your
time!
Scott
