MDI AD CS sensor not switching from removed DC

We are in the process of replacing our Domain Controllers.

What I found is that the MDI sensor on our PKI server is still stuck with a domain controller which has been demoted and removed from the domain.

(Sensor version: 2.250.18972.18405)

I guess, if I reinstall the sensor, it will find a new domain controller - but what if it finds a DC that is to be decommissioned? Should I reinstall the sensor until it choses a "new" DC?

Thank you in advance,

Daniel

    You don't need to reinstall, you can select a different DC using the portal when editing sensor settings in the sensors list.

    You can also reinstall, during deployment the deployment tool contacts the DC locator to select a DC, so it should select a working one, but I think it's faster to just change it in the portal, also if you have a preference on which DC you want it to work with.
