Client Communication Issue

Have a few clients not communicating to SEPM. Clients are not cloned but we do use an imaging process to deploy new systems. In fact, this systems were imaged and deployed over the last few months and only found them in a outdated virus def report.

Running “Troubleshooting’ from the client, I see the following:

1-      In ‘General Information’ the server is offline.

2-      In ‘Connection Status’ it displays ‘Connected.’

Also, no green dot on the tray icon.

Things I’ve done:

1-      Tried replacing the sylink.

2-      Even though not cloned I ran ‘RepairClonedImage’ process.

3-      Ran Cleanwipe and reinstalled.

Thank you for any help!
