Often many people ask me if is possible add SBS 2008 to an existing Windows 2003 standard domain without Exchange Server. The short answer is Yes, using the answer file.

Terms and definitions
Destination server: The new server where you are installing Windows SBS 2008 and migrating your settings and data to.
Source Server: The existing server that you are migrating your settings and data from.
Here is what to do:
1. Install Microsoft .NET Framework Version 2.0 Redistributable Package (x86) on your source server (In my case, I have a 32 bit server). You can download it from here:

2. You remember to change your password to meet new sbs 2008 requirement and also synchronize the ADRM password with administrator password.
If you need to reset your ADRS password, follow this KB:

3. Insert SBS 2008 DVD in your source server and click on "tools" and than click on "Sbsafg.exe".
We can create and save a migration answer file for Windows SBS 2008.
You must copy the migration answer file to the root partition of a USB flash drive or other removable media. (i.e. Floppy)
4. Raise Domain Funcional Level and Forest Functional level to native Windows Server 2003 (on source server)
5. Insert Windows SBS 2008 DVD1 in the DVD drive on the Source Server.
When the Windows SBS 2008 installation wizard starts, click Tools, and then double-click SourceTool.
It runs Adprep.exe, which extends the AD DS schema and updates permissions as necessary to prepare a forest and domain for a domain controller that runs Windows SBS 2008. The AD DS schema in Windows SBS 2008 is not the same as the AD DS schema in Windows SBS 2003 or in Windows Server 2003. To successfully complete the migration process, you must update the AD DS schema on the Source Server if it is running Windows SBS 2003 or Windows Server 2003.
After this step the tool return an error, this is usual because an Exchange Server is not installed in the Source Server.
6. Now insert your Usb Key or Floppy in Destination Server and you Start installation process from SBS 2008 DVD.
7. After that unattented setup has finished you can configure your users and groups for SBS 2008.
All Windows SBS 2003 security groups and distribution lists are migrated during the initial migration of Active Directory Domain Services (AD DS). However, the migrated security groups and distribution lists are not automatically displayed in the Windows SBS Console. To manage these groups, you must assign the Created value to the msSBSCreationState attribute for each group—either automatically, using the Windows Small Business Server 2008 Active Directory Group Converter tool, or manually, through the Active Directory Security Interface.
