Not at all.
StatServer receives the monitor start event from TServer, so lets start here. Delete the DN, and recreate and associate to the place.
Check Tserver logs for this recreation action, you should see the startmonitor event.
Then See StatServer and see what it reports.
Now, if everything is ok, try to do some actions at the extension (hookup, ring, callout, etc) verify Statserver is monitoring your extension, by the way be sure to monitor the StatServer that you are using in your strategies, normally reporting Statserver is a different one from URS.
Now, loggin an agent, check TServer events, check Statserver events and now URS events. You will see the agentlogin action in all of them and ready to receive interactions from URS.
In CCPulse now you should be able to see the agent logged in, but be sure for this time only to select as STatserver the one that URS uses and create a workspace with only your DN and agent involved here.
Check the agent extended monitoring status and you should see that he is logged into the correct DN.
Now create a strategy that only sends the call to this agent, what does URS, Statserver and TServer logs say?
If you find any trouble post the logs here with ConnID and called/Calling extension involved and what you have done and where you found the error.
