Is it possible to change AD Domain name. Windows 2008 with SCCM 2007, Wsus, FEP 2010

Well the title says it all. I used the instructions on this site to setup all the above. (Thanks to all for that)

 

Now my boss wants me to deploy this test machine to our clients just to show that it works.

 

We are thinking of using it as a ADC at our clients premises. Unfortunately, in our test environment, we created a domain with the same name as our clients current domain.

 

I am confused if I can add an ADC with the same domain name or do I have to change the name to something else before I add it as ADC.

 

Complete noob here.

Cheers
