I find it very annoying that sometimes when I clear an PXE Advertisement from the SCCM console and I reboot the machine I still get the PXE Boot Aborted message… a small workaround I always use is the following.

• Clear the PXE Advertisement using SCCM console
• Stop the WDS Service on the SCCM PXE Server
• Clear RemoteInstall$\SMSTemp on the SCCM PXE Server
• Start WDS Service on the SCCM PXE Server

And voila! The advertisement does work this time around…

All in all I have experienced a lot of troubles with PXE and SCCM… I am really hoping the next version of SCCM will bring major improvements to this part….
