No modifications to the network or the computers. The computer is able to obtain an IP address in windows, link speed auto-negotiates to 1Gbps. I tested the network path and it had no issues, but just in case I switch to a different port. The issue still remains.

I Just noticed that the links to the screenshot on the original post are broken. Here are new links to the images:

This is the error I get when a computer is trying to execute a task from fog and it goes thru PXE:

Description of Problem:

After updating to the latest version, I noticed that the speed decreased. The image size being pushed to the computers is about 300GB, this used to take between 2 and 3 hours. Now it is taking about 8 hours. I also noticed that some of the computers fail to image. The computers get an IP address from PXE and continue to load but then give an error saying that it could not obtain an IP from the DHCP server or is unable to reach the FOG Server.

I canceled the task and tried to launch it from the client machine PXE menu, and got the same error. I launched the FOG compatibility from the PXE menu and noticed that it was unable to get an IP address. I loaded the computer back into windows and the computer was able to connect to the internet with no issues. I have 3 rooms of 24 computers in this particular area and about a third of them have this issue. The other computers were able to be imaged but noticed that the PXE loading was very slow and the time that it usually takes to the image was doubled. Here is a screenshot of when I tried loading the computer compatibility from the client PXE menu.

I tried Switching to older kernels and it did not work. I would appreciate any ideas that can help in figuring out this problem.

Sorry it took me so long to get back to you, I tried using the file you suggested and to no avail. The same problem occurs. I also used a different fog server and it had the same behavior. The computers randomly freeze loading pxe drivers.

@george1421

I tried different version of the kernel and they all do the same. I am willing to try different version of the PXE files

@wayne-workman Hello, sorry it took me so long to get back to you, Here are the pictures you requested.

@wayne-workman

I tried the kernel you suggested and it did not solve the problem. I also tried changing the pxe boot in the DHCP to these:

undionly.kpxe
ipxe.pxe
ipxe.kkpxe

These did not work with the suggested kernel.

Thanks

Thanks for the quick reply I will try to play with the kernels.

Having issue when computers boot from pxe. They randomly freeze and do not continue to boot. They stop at different points when loading PXE. I am not sure how to proceed in troubleshooting this issue, any help will be appreciated. please see my configuration below, please let me know if you have additional questions.
