[SCCM 2012] Forgetting Wired MAC Address?
We're using SCCM 2012 to image all our computers and have been since last summer. What we've found over time is that SCCM seems to "forget" the MAC address of the wired nic of laptops who only use wireless for connecting. Seems like it would be fine since it does update the computer's record with the wireless MAC address and software deployments work fine over wireless.
The trouble comes in when we want to reimage the computers using PXE and have to use the wired card. It doesn't work seemingly because SCCM doesn't recognize the MAC address. On the flip side, we have SCCM setup to "ask" if an unknown computer should be image (we have an optional deployment setup for unknown computers, so you have to hit F12 to get it to run on PXE boot) -- but the computers SCCM "forgets" don't ask to take the optional deployment. So in reality, SCCM isn't forgetting the wired MAC, it's just not using it. Any suggestions on how to get SCCM to keep the wired MAC address "active" without telling teachers to plug the laptops into the wired network periodically?
My techs and I have tried searching, but we're either using the wrong keywords or no one else is having the issue -- which I find hard to believe.
