Question Creating Mixed Environment - Windows 2008 & 2003

I'm setting up a mini network in the office with 3 servers for remote workers:

Windows 2008 Enterprise - Primary work machine

Windows 2008 Terminal Server - hold the licenses for the users

Windows 2003 Active Directory Server - the primary AD server

Is there anything special I need to do here?  I had read something about "adprep" (I believe) being run on the 2003 machine to bring it up to 2008 standards on A/D.  Is this something I should do?

Are there any downsides to doing this vs. A third 2008 machine?  (I'd rather save the cost of a third license, we already have the 2003 license).

Thanks

Is this an existing Domain? If not you don't need to worry about Windows 2003 Server getting adprep. If you are going to install Window 2008 Server has a domain controller on the Windows 2003 server then you would need to run adprep

Information about adprep http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/A_3644-Windows-2008-Server-R2-adprep-adprep32.html

You can have a mix environment that is not a problem

Only use adprep if u currently have an existing Win2k3 AD.  If not just build ur Win2k8 server and promote it

Since this is a small environment with a single DC I doubt you would need the benefits a 2008 DC will give you, *if* you have a low budget.

This is a brand new AD.

We have two new Windows 2008 servers (one 2008 standard 32 bit, one 2008 Enterprise R2 64 bit ... don't ask me why we got one that is 32 bit)

So on the AD controller - I can do 2003 (which we have and are not using) or if we must, go for 2008.

I'd rather save the $ and use 2003 ... I just don't know if there is any downside to it.

Well, if I am starting out fresh and make my AD server W2k3, do I need to use adprep ?

Thanks

If you are starting out fresh with Windows 2003 Server you would not need to run adprep unless you are going to a Windows 2008 Server as a Domain Controller. If you are then yes you need to run adprep to add a Windows 2008 Server as a Domain Controller. I recommend having at least two Domain Controllers

I checked and the version of 2003 Server we have is:  Small Business Server 2003 R2

I've looked at http://en.wikipedia.org/wiki/Windows_Small_Business_Server and it appears that you CAN use this IF:

1 - there is only one SBS in the forest and
2 - the SBS server is the "root of the Active Directory forest."

Is this correct?

Is there any downside to using this server for this purpose?  This is literally the ONLY thing the server would be used for - to run the Active Directory.

Thanks

That is correct what you found on wiki.

In a small environment, you should be fine using a SBS.

You would need to run SBS 2003 as your primary domain controller that is part of the edition this server must be master but overall you should be good to go with this version

I also saw on the Microsoft comparison page a half-shaded circle for 2003 Web Server edition.  Does that mean Windows 2003 Web Server can be a member of an AD but not a controller?

I checked and we also have a copy of Windows Server 2008 Foundation.  Is that essentially 2008 Small Business?

Darius GhassemCommented:
Web server can be part of a domain but can't be domain controller. Web edition can only be used for limited functionality for Web services.

Windows 2008 Server Foundation is kind of like SBS but not.
