You think you need one Server do you?

If you read the marketing spiel a Windows Server will do 1000 things. If you try to use a Windows server however you may easily find that you need, in fact 2, 3, 5 or 10 Servers to do all the work that is asked of it.

Take a look at the Terminal Server Farm here:

I dont even know if the Domain Controller is listed, much less the backup Domain Controller.

One Server for Licensing. One Server for Load Balancing, etc etc. Dont forget DNS. Don't forget Wins. Don't forget.. ad infinitum.

All this takes a lot of time to implement, not to speak of hardware and licensing expense. And then there is power. Virtualization helps, but the last I read, certain roles are not recomended for virtualization.. Domain Controlling is one. The Slowness of Virtualization would call into question having your Terminal Server be virtualized. Maybe the licensing server. Perhaps a backup Domain Controller, the DNS server etc (why are those not part of the primary Domain Control Role anyway). I suppose they generally are, but redundancy makes its call.

Terminal Services are, for sure, great tools. A functioning server can generally be accomplished more easily than the picture shows. Still, some very high costs are out there, especially if you are pushing the OS up from the client level.

Time to research VNC again.
