If you are trying to capture an image, you might see the following

The client boots into the initial boot environment with the SCCM splash screen, then preparing network connections appears briefly - this all disappears, then the client reboots - first step is to re-run the advertisement and press F8 when the SCCM splash screen is up, have a look at the SMSTS.LOG, you will see

Found 0 DPs in subnet, 0 DPs in local site, and 0 DPs in remote location

Failed to resolve selected task sequence dependencies. Code(0x80040102)

And then you will kick yourself as you have not distributed the image to any DP's
