"Stop 0x21a" Error Message Occurs If You Download a RIPrep Image

If you download a Remote Installation Preparation wizard (RIPrep) image from a Windows 2000-based server that is running Remote Installation Services, you may receive the following error message:

This issue may occur if any of the following conditions are true:

• Windows 2000-based server that is running Remote Installation Services contains a Windows Preinstall Environment (WinPE) image.
• The folder name in which the WinPE image is stored is listed before the name of the Windows XP backing flat image (the image that is created when you run Risetup.exe) because the first letter of the folder in which the WinPE image is stored occurs earlier in the alphabet. For example, the WinPE image is stored in the following folder:
  D:\Reminst\Setup\Language\Images\Winpe.xp
  The Windows XP backing flat image is stored in the following folder:
  D:\Reminst\Setup\Language\Images\Xp.rtm

To work around this issue, rename the folder in which the Windows XP backing flat image is stored to a name that starts with a letter that occurs earlier in the alphabet than the first letter of the folder in which the WinPE image is stored.

If you are loading a RIPrep image, the Remote Installation Services Boot Information Negotiation Layer (BINL) service looks for a matching backing flat image so that the service can start. After the service starts, it starts the network, and then copies the image to the local hard disk. The BINL service scans the Reminst\Setup\Language\Images folder alphabetically as it looks for a matching Ntoskrnl.exe file. Because WinPE images are a subset of the Windows XP files, the BINL service finds a match, and then selects this image.
