It would be useful to get the MAC address (or convert the netbootGUID attribute to MAC address) from computer objects discovered in AD.

In our environment, new computers are prestaged in AD which then end up discovered by system discovery and added to SCCM. Existing computers which have not had the SCCM client installed are also discovered and added to SCCM. However, when either a brand new machine or existing machine without the client installed needs imaged, the existing object in SCCM needs deleted, and then a new object needs imported with the MAC address so the machine can PXE boot.

If the objects discovered from AD included the MAC address attribute or could convert the netbootGUID into a MAC address for the SCCM object, these machines could be PXE booted without having to delete them and reimport them
