@bc601 There is a section in the FOG Client page on the wiki that talks about what needs to be done if you install the fog client before you sysprep it here: https://wiki.fogproject.org/wiki/index.php?title=FOG_Client#FOG_Client_with_Sysprep
Or you can install the fog client post imaging using the msi and the setupcomplete.cmd file. Two ways to go about it to get the same results.
