Landesk Agent doesn't work after deleting from MMC

Hello everybody!

I have a Problem on our Management Console. When i delete a Client from the "All Device" view it doesn't show me any Information anymore after returning.

Do you ever had this Problem and if Yes... do you have any answer for me how to resolve it?

I tried to uninstall the Client and reinstall it completly from the System. Inventory and Security Scan works but the Information are not updating on the MMC.

We work with LD 9 - SP 3

Hope i explained the Issue in a easy way. If you have any questions- don't be shy and ask please

Looking forward for answers.
