@Wayne-Workman Thanks for your response; I don’t know how specific you need me to be but we are 90% Dell.
Generally speaking, there’s at least one Optiplex 780 (2012?), a few Optiplex 3010’s (2013), and 3 or 4 Dell Latitude E6520’s (2011). Our Network Engineer suggested maybe a certain brand/model of NIC’s…

@MJR Correction; the Quick Image worked (after turning back on PXE) , it apparently just hung on the final reboot in the same place it always does.

Microsoft AD environment with 200+ computers. Upgraded fog server to 1.2 from 0.32. No previous similar problems.
On approximately 10% of campus computers, we are also seeing the “perma-blinking” top left cursor after
the Fog Menu screen during PXY boot. Laptops and Desktops running Windows 7. Have to turn off PXY boot
for work around. Today tried my first Fog “Quick Image” on a Dell Latitude with this issue and it also hangs about
15 minutes into the reimage on the same blinking cursor screen. Hoping for some information, directions, questions.
Thanks very much.
