Image creation, upload, and deploy appears to have worked successfully.
The test machine received the deployed image, the sysprep answer file was performed and a local account created successfully. Drivers appear to have been pushed/installed as expected.
However, the machine itself does not show in TOEMS web-dash under computers, and the post-deployment group scripts (domain join really being the only one I need here) have not been run.
Where do I start to track down why this happened and/or how to resolve?
If I search for the machine by name, I do find an older reference to it under Computers, but this appears to have been from the first test run I'd performed (it was later deleted, and re-deployed after I resolved the driver-injection issue).
