SYMPTOMS
You install Microsoft Windows Server 2003 Service Pack 2 (SP2) on a Microsoft Windows 2003-based computer that is running Remote Installation Services (RIS). Then, you try to start a Pre-Boot Execution Environment (PXE) client session. However, you receive an error message that resembles the following:

PXE-E3B: TFTP Error

File Not Found

Note The error message may vary depending on the BIOS of the PXE client computer.

<div class="cause_section">

CAUSE
This issue may occur in a scenario in which you did not add the Windows Vista image at the time that you configured Windows Deployment Services (WDS) on the Windows Server 2003-based computer.

When you configure WDS, you are prompted to add images to the WDS server. If you plan to add a Windows Vista image, you have to point to the Sources\boot.wim file that is located on the Windows Vista DVD.

But if you decide not to add a Windows Vista image, the WDS server is already configured to use the PXEBoot.com file instead of the Startrom.com file to start a PXE client session. Therefore, the WDS server searches for the PXEBoot.com file in the following folder:

remoteinstall\boot\x86

If the WDS server cannot find the PXEBoot.com file in this folder, you receive the error message that is mentioned in the &quot;Symptoms&quot; section when you start a PXE client session.
