After installing Windows 2003 and required updates on your virtual machine, we now need to prepare it for easy duplication later. Now extract files from system preparation package, which we had previously downloaded. As we have installed Service Pack 2 for Windows 2003, so we will use only preparation package related to that.
Now run “setupmgr.exe” from the extracted files. This is a setup wizard which will help you create your configuration set and answer file for automating your duplication process.
