TS only available when booting from ISO, not from PXE

Question

Try to deploy a TS to a computer that I had manually imported with the MAC address. The computer is member of a collection "OS Deployment". The TS is deployed to this collection (Required, config manager clients, media and pxe, always rerun program).

When PXE booting the computer, the following is logged in smspxe.log:

When booting the same computer from an ISO that I have created from the same default SCCM Boot image, the TS is available and can be started.

Thought that there is a PXE Boot problem. But I have then deployed the TS to "unkown computers" and deleted the manually imported system. After that, PXE boot works and the TS is offered to the same system.

Any advice? Thank you all in advance.

Answer 1

Notice the line before the one you highlighted? Did you clear the Required PXE deployment for the resource (or collection)?

I strongly recommend against using required deployments for OSD TSes. Required deployments to unknown computers have very little value and just open you up to problems as someone has to initiate the PXE or boot image boot anyway so you're not really eliminating anything or enabling any novel or useful scenario(s).
