I have ran into a situation where I can no longer harvest new machines from AD.

I have tried to remove and add back the probe agent with no joy.

Am I right in thinking that once i have removed the Probe agent I will need to Uninstall and Detach Org as well?

I saw the payload which means it will break any VSA user created from this Discovery as well.

Any advice would be grateful.

This being the case, it would always make you think that a non AD based Admin account is the best way to go in any case because of the dependancy.
