Imaged PCs not reporting in correctly?

Imaged PCs not reporting in correctly?

We have starting using OS Deployer to image our PCs.  We have the Endpoint Agent installed on the image machine/file.  We followed these instructions Imaging Computers with Endpoint Central Agent on them (manageengine.com)   

We're seeing an issue with the Endpoint Agent not phoning home after a new image is completed.  This happens to at least half of the installs.  The other half connect to the Endpoint Management server just fine.  Anyone have any thoughts or suggestions?
