Tftp timeout on Dell PC's only

[CoxM]

Hi All,

I am getting a tftp timeout when I try to image a couple of our Dell Optiplex PCs. If I do Lenovo computers then they work fine.
I have been through BIOS and confirmed settings.

Any suggestions as to what the problem might be would be super helpful, not sure where to go on this one.

Thanks.

Would you share a screen shot of the error you see on the Dells?
Also what model of Dells do you have issues with and lastly what version of FOG are you using?
