I think that what I want to do is feasible but I'm not really sure. I have a production NT network located in 3 states and 1 foreign country. There are 8 different domains one domain has 3 Win2k advance servers running as member servers. I have been task to setup a test W2k domain instead of each location setting up a test domain I want to install a single test domain that the other would join. We would use the exsisting network stucture but with diferent subnet and domain name. My belief is that I can do this with no impacted on my production domain (used bandwith is understood)this would allow me to run test on my lab domain. Was wondering if anyone has any thoughts on this. Thanks
