I'm running into similar issues. I created an image with an enrol profile on the desktop and the trust profile pre-installed. I used NetRestore to restore the image onto 50 Macs. When I went to enrol, my Profile Manager database had somehow become corrupt, forcing me to rebuild. Thinking I would simply delete the old Trust Profile and Enrol profile, and replace them with the new versions, each client is getting this message when attempting to enrol.

I've gone so far as to clean out the keychain but the issue persists. What's really weird is the device does enrol, and downloads all the applicable profiles - BUT it doesn't receive any push settings afterwards. e.g.. If I choose to change a setting in Profile Manager - the activity hangs with the status "Pending"
