How to reset Diagnnostics Agent configuration

Hi,

I have host with installed Diagnostics Agent. First time on this host was installed managed system A and DA was configured for it. After that system A was uninstalled and installed system B. DA was configured for system B again. In Intrscope EM I have old destionations to system A.

How to delete old destination to system A or reset completly DA configuration?

Thanks a lot,

Alexander
