I'm running SCCM 2012 on Server 2008 R2. Currently we have a standard task sequence we use for all of our Windows 7 deployments that is working fine. We use PXE boot to load up WinPE to select the task sequence to load and all is good.
I've made a new task sequence to deploy custom configuration settings to a group of computers. I've duplicated much of the original task sequence, using the same boot media. After i deploy the new TS to the All Unknown Computers collection, PXE boot does not work anymore.
It downloads WDSNBP, starts by DHCP referral, contacts the server. After that I just get a Pending Request ID: number says contacting server then fails. If i go back to my new TS and delete the deployment, all is good again.
Can i create a new task sequence using an existing reference image? Has anyone seen this type of issue before? I see similar issues online, but it seems to be for people that cannot PXE boot at all. My problem is just that the new task sequence seems to kill PXE boot when it's deployed.
