Hey guys, I have a quick (hopefully) question. We have a production domain however, we want to configure a test domain (from scratch) within our network. We have a PDC already for our domain and we are curious to know if setting up RRAS on our test DC with two seperate nic cards, one nic to the company domain and another nic to a switch that has other test servers, if it will cause any problems with our production network. If someone can elaborate on how this can be done, would be greatly appreciated.

Something like this, http://support.microsoft.com/kb/255248

We do not want to promote this "test" DC into our production network, we simply want to be able to virtually have a whole other domain we can use to test RADIUS and other technologies on a different subnet, yet ability to allow all devices use the internet from the company

I'm pretty sure you can't do that, i think what you could do is have another router and set up routing on it to forward the packets to the switch.But i am no expert on this, so not much good to you i know!-

To start you never want to put a test domain in your existing forest/domain. That is asking for all sorts of trouble as you conduct tests and change configs. You would start with an internet gateway router that could support multiple subnets. SOHO routers can't do this. You can use all the same hardware ie. switches etc though it is best if you vlan as well as subnet to provide a true barrier between the two networks. You would bring up a new Forest and domain in that forest. This would require at least one DC. And there you have your test domain that you can trash at will [then recover] with no impact on the live company network.

Yup i was going to say that SOHO routers don't support manually configuring routing, If you are desperate you could buy a second hand cisco router from ebay, setting up routing is very easy to do on them. But you'd better get advise to make sure you were buying a cisco router that meets your needs as there are quite a few different versions.
