Step 33 – dcpromo-ing down the SBS 2003
In my real migration at the office, at this point in the migration I turned off the SBS 2003 rather than immediately dcpromo-ing it to ensure that I hadn’t forgotten anything still hooked to the SBS 2003. Remember you will be removing this server and having to reinstall it. You cannot dcpromo down the SBS 2003 and leave it as a member server.
To demote the Source Server
1. On the Source Server, click Start, click Run, type dcpromo, and then click OK.
2. Click Next twice.
Do not select This server is the last domain controller in the domain.
3. In the Summary dialog box, you are informed that AD DS will be removed from the computer and that the server will become a member of the domain. Click Next.
You’ll be prompted to put in a password..
4. Click Finish. The Source Server restarts.
5. After the Source Server restarts, add the Source Server as a member of a workgroup before you disconnect it from the network.
