32-bit and 64-bit Windows: frequently asked questions

Can I run 32-bit programs on a 64-bit computer?
Most programs designed for a computer running a 32-bit version of Windows
will work on a computer running 64-bit versions of Windows. Notable
exceptions are many antivirus programs, and some hardware drivers.
Drivers designed for 32-bit versions of Windows do not work on computers
running a 64-bit version of Windows. If you're trying to install a printer
or other device that only has 32-bit drivers available, it won't work
correctly on a 64-bit version of Windows.

The plan was to put Windows Server 2008 (32-bit ver) on the DC and SBS 2008
(64-bit incl. Exchange 2007) on the member server.
Our domain controller only runs two business packages (32-bit only - not
64-bit compatible) and simple file sharing.
The issues I have are as follows:
1. If I have the DC as 32-bit and the Exchange server as 64-bit will there
be any incompatibility issues?
2. Will I be able to install and configure Exchange 2007 on the Exchange
server (SBS 2008) as a member server and configure it to access Active
Directory on the DC?

YOU CANNOT DO THIS. SBS *has* to be a DC and has to hold all FSMO roles.
You cannot install SBS as a "member server."

That does not answer my initial question. Why are you running apps on your
domain controller? Why not run the apps on a member server instead?

Already answered. SBS is 64-bit only and SBS has to be a DC. So the
scenario you point cannot exist.

Again, no. Exchange is not a separate install in SBS. It is installed as
part of the SBS installation process and that includes the OS, Active
Directory, and configuring all the domain controller stuff.
It increasingly sounds like you are looking at a migration scenario, even if
you don't know it yet. You should look at migration docs for SBS 08 on
technet, understand what role SBS will be playing in your network, and then
proceed from there. Ideally you'll have SBS-08 running on one server and
have a separate 32-bit server for your apps with no conflicts at all.

Ok. Isn't it best practice to keep Exchange off of your domain controller?

Currently we use our domain controller for file sharing and apps and we use
the member server for Exchange. Running our apps on a third member server
would be overkill for a business our size in my opinion. Not having anything
running on the DC (apart from DNS, DHCP etc) would be a waste of resources.

thanks for your advice on this so far

Domain Controller - SBS 2008 Premium - 64-bit
Exchange Server 2007
Member Server - Windows Server 2008 (licence included with SBS 2008 Prem)
SQL Server (licence included with SBS 2008 Prem)
Our line of business apps
does anyone have any views on this configuration?
