Sorry to Hijack but I am having an issue that is similar.
I am unable to Distribute my Task sequence to my DP. All other content is distributed, boot images, os installers, os images, etc. I was able to distribute it one time and get the pxe boot to work but mid way I got an error that I believe to be due to me changing a setting in the task sequence while it was running. I went and disabled reboot computers in PXE. I did this out of fear that it would somehow reboot an unknown computer on my network and wipe the os. Now I understand that cannot happen.
But ever since that happened I am unable to distribute my task sequence and also I do not see it when I go to content status.
Any help is greatly appreciated.
Thanks.
