Gidday.
We have a customer running a several Windows 2000 servers. The site has
recently connected via a VPN to the international offices and are in the
process of migrating many services to them.
Initially however there is a requirement to access servers across the WAN
using DNS name resolution.
I have configured the current LAN DNS server on the DC to forward requests
DNS to external DNS Servers.
DNS Order
202.27.184.3 (ISP's DNS Server)
155.250.19.111 (Companies International DNS Server's)
202.27.184.5 (ISP's Secondary DNS)
Now my problem is that if I set the ISP's server as the top forwarder I can
ping. www.google.co.nz and resolve it successfully.
However if I try to ping a internation company server say rcweb.company.de,
I receive Unknown Host errors.
I can change the DNS order to be
155.250.19.111 (Companies International DNS Server's)
202.27.184.3 (ISP's DNS Server)
Under this scenario I can pint and resolve rcweb.company.de, however can no
longer resolve www.google.co.nz.
So there DNS server is not automatically dropping to the next forwarder
entry as required. I have attempted changing the the DNS timeout from 5
seconds to 1 with no change.
The server is Windows 2000 Server Standard with all the patches and updates
loaded.
Your help is appreciated.

Daniel Goymer
