DNS Server Use order

[chosen1]

My users need to have these 3 DNS entries in their Win2k client setup, exactly in this order. For example:

A
B
C

A and B are identical to each other.
C is in a different region.

These DNS servers are maintained by 2 different data centers.

I don't have any authority over them.

The problem is:

1 - "A&B" are able to resolve internet/intranet requests properly but cannot resolve "*.session.rservices.com"

2 - "C" can resolve "*.session.rservices.com" but internet/intranet stuff is resolving to the wrong location(NAT Address) and thus won't work.

My users need "C" to resolve "*.session.rservices.com" requests because of an app they need. So when all 3 DNS entries are in the client setup, everything works 85% of the time.

The other 15% of time Intranet/Internet access is intermittent. Seems that those requests sometimes use the DNS "C" to resolve and it fails. Likewise requests for "*.session.rservices.com" work mostly but there is a chance it won't work as it might use A&B to resolve.

Is there a way I can somehow prioritize the DNS search usage in Win2kPro? For example to force requests for "*.session.rservices.com" to only use DNS "C" and never A/B?

Thanks for any insight into this

If you only want a certain group of users to use only "C", then don't put A & B in there network settings. Good luck.

Wish it was that easy but...
A&B are needed in their network settings otherwise the users can't get internet/intranet

Create a sub-zone in A&B for "*.session.rservices.com" and set them as forwarders to C. That way whenever you have a client in A&B's DNS region requesting "*.session.rservices.com" resolution, A&B will forward that query to C regardless. Good luck!

Alternatively you can use a hosts file, you can add it to their login scripts.

PC will resolve hosts (and LMHOSTS) first before they will look for DNS (or WINS).
