I'm trying to get PXE booting to work on our SCCM 2012 R2 server and am getting the dreaded "PXE-E53: No Boot file Name Received." DHCP server is in same subnet on a different machine, so supposedly no DHCP options or ip helpers are necessary. I'm testing using a client VM with the legacy adapter for the NIC, and that machine PXE boots fine from our SCCM 2007 server.
When I test, I've been shutting down the SCCM 2007 server so that the 2012 machine is the only PXE server on our network.
In a nutshell, I'm trying to deploy Windows 8.1 using this as a guide. The x86 and x64 boot images are enabled for PXE distribution and I've deployed the task sequence for the 8.1 OS image to all unknown computers. The DP shows content for the OS image and the boot images. PXE on the DP is enabled and checkmarked to listen for PXE requests on all interfaces and for unknown computer support.
For troubleshooting I've tried unchecking all the PXE settinging in the DP, which removes WDS and then putting it back, as well as removing the MP role and putting it back (see attached snippet of SMSPXE.LOG).
I feel like I'm missing something basic here. Can anyone help?
Thanks!
