During a lab setup last time I wanted to deploy two active directory sites where I could deploy two different Exchange Server 2007 HT roles. I found it little difficult to achieve using windows RRAS. I was seeking for a routing software that could meet my complex needs. Windows RRAS definitely offers enough configurations those can be used to deploy a test lab at least. But, on the other hand it fails on working with lower resources and needs more memory and disk resources compared to what you need.
If you are seeking to build your own labs and deploy 2 or more AD sites in it also running low on resources. You may find FreeSCO very useful.
This is an open source utility you can use with a Linux or a UNIX box. If you are thinking that you are hardcore Microsoft guy and you wont be able to use it on a character user interface system like Linux and Unix then you really don’t need to be scared about that. Its a fairly simple installable program that can be configured using given documentation on www.FreeSCO.org What all you need is a little bit of knowledge of Linux and you should be good to go. I tested it on my VMware 6.5 labs and it really works great!
Thanks to the guys who developed it.
