The WDS Service Fails When the PXE Filter Is Installed
Problem: The WDS service does not work as expected after you upgrade from a previous version of MDT to MDT 2012.
Possible Solution: If the previous installation of MDT used WDS PXE Filter support, you must remove this support to allow the WDS service to work as expected. Use the Remove WDS PXE Filter Wizard to remove support.
Note To access the Remove WDS PXE Filter Wizard, click Start, and then point to All Programs. Point to Microsoft Deployment Toolkit, and then click Remove WDS PXE Filter Wizard.
