How to configure a PXE Representative to only respond to certain devices

Issue

How to configure a PXE Representative to only respond to certian machines devices.

Resolution

1. Create a text file on the PXE Representative called ALLOWED.TXT at the root of C:\.
2. Place MAC addresses (without dashes) in ALLOWED.TXT, one MAC address per line.
3. Machines whose MAC addresses are listed in ALLOWED.TXT will receive PXE replies to their requests; MAC addresses not in ALLOWED.TXT will not receive PXE replies and therefore will not boot.

Note:

You can also create a DENIED.TXT, follow the same instructions above (place it at the root of C: and one mac address per line). If a DENIED.TXT and an ALLOWED.TXT are both at the root of C:, then the ALLOWED.TXT will be used and the DENIED.TXT will be ignored.
