SYMPTOMS
When you boot a system, it boots successfully into iPXE land but you then see a message stating that there are no available deployments for the device.
 
TROUBLESHOOTING STEPS
Firstly, run the 2PXE Service in 'interactive' mode. Go to the 2PXE service installation folder, find the executable (2Pint.2pxe.Service.exe), right click and select 'Run as Administrator' This will then output debug information in real-time.
 
Then, boot the system that you are troubleshooting.
 
You should see something similar to the below image:
 
 
 
 This is a fairly common troubleshooting issue, so here are some things to check and some SQL that you can run which will return the available deployments based on the MAC Address etc.
 
  • Is the Boot Image distributed to the Distribution Point where 2PXE is installed?
  • Is the Task Sequence Deployment set to be available to 'Media And PXE' clients?
  • Is all referenced content for the Task Sequence distributed to an accessible DP? 
  • Boundaries - do you have DP affinity set that might exclude the system from this DP?
 
If you have checked all of the above and it's still returning nothing - you can  run the SQL Query below. It's basically the same as SCCM runs when you boot a system 
Just insert the correct MAC and SMBios GUID, which you can get from the interactive 2PXE session (above)
