#HOW TO USE 24 HR NIGHT SHIFT MAC UPDATE#

These are focused on creating a new custom resource type and adding custom attributes to an existing computer resource but you can modify the examples to update an existing attribute on an existing computer/system resource including the MAC Address (as this is exactly what heartbeat discovery does). What's wrong with creating a new resource though? Are you using static collection memberships for this resource?įor some info on creating a custom DDR see the following: Yes, it is true that this removes the end-to-end unattended nature though. This only happens for available deployments though - I would never, ever require a deployment to unknown computers. Pressing F12 (BIOS) or Enter (UEFI) is part of the network boot program (NBP) and not WinPE. If there would be some, even ugly way to change mac addresses, it would be better than the situation as it now is - something that may intentionally change, because it is changeable not being changeable within sccm.įor the pre-start command, you'd have to use boot media and not PXE - sorry, didn't call that out.Īnd sorry, but your paragraph on first boot doesn't really make sense (to me at least). You can certainly file a uservoice item on this though. You could create a custom DDR and this should be able to change the MAC but that's not a general recommendation, just a technical possibility. You can't directly change the MAC address in a resource. SCCM will then fall back to booting WinPE directly again, triggering a new provisioning cycle. You can revert to the firstboot behavior by just deleting this change. If someone presses a key it boots into PXE. As soon as WinPE reports it has installed and first time started sccm reconfigures PXE for this one client to wait until some key is pressed. It will in all cases boot from network and start WinPE from there. It would not be unattended any more.īut by the way: the first boot, defined as the first boot image was not successfully applied to the client - no successful start of the WinPE environment, there is no such question to press any key to boot from network.

Neither is acceptable, because you'll have to lunger around until the install starts from the right system.

Say I provision one system it might install some Unix but it might even install some Windows or try if it could execute phone software written for MIPS. Setting unknown computer support to enabled and then relying on "has to press a key to have the system install" renders any boot and provisioning to something that might work or might not.

WinPE would not be loaded and the new resource would never get registered. Since the mac address is not known to sccm it will never react on this dhcp boot request. This would not help: WinPE is loaded by PXE, initiated by dhcp. Before unknown computer support was added in ConfigMgr 2007 R2, this is exactly what we had to do. For this command, you'd have to create a script to register a new resource for the system on-demand. If not, then you'll have to use a pre-start command that runs in WinPE before the task sequence engine is initiated. If not possible via GUI - any commandline tool that could do? I'd like to have a way to change the mac address for clients on sccm. I'd like to only change this mac address and then be all set again!īoth of the other systems booting clients via network allow for such a change. And not by deleting the client and building a new one. I'd like to change this address within client configurations to make sccm match this client again.

Sometimes this is virtualized hardware and this mac address changes. But for all of them I could turn off "unknown computer support" making them to react only to those requests to dhcp the servers are made known of.īut now I do have one real problem: sccm does not allow to change, as far as I could find, the mac address.

All of them expect to be alone on the network, but this is not possible. One for Unixes, one for Windows and one for phones. This would enable it for all - and I do not want to say provision a system I do not control.Īt the moment there are three systems allowing to boot from. But just exact this could happen with unknown computer support enabled. You do not await your device boot something quite different than you expected. These systems would try to boot what sccm then provides on a base of "whoever is faster". Enable unknown computer support will boot some systems dhcp is enabled, but they are waiting for some boot image from an other server not under sccm control.
