No SCCM 2007 clients report in on the console

Check out the Client Logs under C:\Windows\CCM\Logs
Missing Actions are are sign for a communication or configuration error between Management Points and Clients.
Especially have a look at the ClientIDManagerStartup.log
Boundaries for the Branch are Ok?
Management Point shows no errors? (Check your Site State and download the MP Troubleshoort from ConfigMgr Toolkit)

Please forgive my late response. I manage our Netapp storage applicnae and after a DOT upgrade we had several issues. Here is some info form a client log it appears to be registering correctly:

The issue was resolved by upgarding the version of sccm 2007 and that was not given as a solution.
