Hi folks,

I built a windows 2003 DNS server with a primary DNS zone which is
configured to allow dynamic updates. All the machines (XP) on the
network (no domain, workgroup) can update this DNS with their IP
addresses.

I have a machine (XP) which is on a GPRS modem, it connects to my
network via a private GPRS link. I have set the GPRS machine up with
the DNS IP address of the above server, I have enabled within the DUN
properties "register this client with DNS". But this machine never
updates DNS, any clues?

cheers
Dave

Note

the windows XP clients that are successful are connected via the
network card, static IP addresses are also configured, when I change
the static IP the DNS also gets updated. The GPRS machines are given
their IP by a RADIUS server, only the IP address of the DNS server is
static.

Assuming the XP clients are DHCP clients, is the DHCP server a Microsoft
DHCP server that is using the DNS server (in it's IP properties) that the
other machines are using?

Maybe during the reg process access to the internal DNS has not been
established yet. If you tried an ipconfig /registerdns while the client is
connected via your modem, does that work? Are there any ports or any sort of
traffic filtered?

Excellent! The ipconfig /registerdns works fine from the GPRS client.
Can I automate this to run after the dial-up GPRS connection has
connected?
Does this mean something else is wrong with the automatic dynamic
update?

The other XP clients that work over the LAN do not use DHCP, I have
statically assigned their IP addresses in "Network Connections"

OK I have now used an eventrigger to run a batch file which contains
"ipconfig /registerdns" this works fine, it's not ideal but it does
work!

Is there a reason why the command ipconfig /registerdns works but the
automatic update doesn't?

cheers

It should work. Check under the GPRS interface to ensure the Connection
Specific Suffix (IP properties, Advanced, DNS tab) is set to the zone you
want the machine to update into.
