PXE TFTP Timeout on Certain Machines
We have a weird issue where certain machines are getting "PXE E32 TFTP Timeout" when trying to PXE boot from our FOG box.
However, PXE booting works just fine on said machines if we use a gPXE boot disk - which implies the problem lies with the NICs on the machines. The strange thing is that (so I'm told) this has never been an issue in the past and only started when they moved from a *nix dhcp server to a windows box.
We are using server 2008 for dhcp and have options 66 and 67 set correctly. PXE booting also works fine on the majority of machines, its just several types of machine causing us issues. One thing we have noticed is that the machines with this problem always have Realtek based NICs...
I've had a look around on the forums and googled a fair bit, and whilst some people have had similar problems, we have been unable to find a fix. Can anyone offer any insight? :(
