I have a server running IPCC express 4.0.4sr1.
A second server had been installed in the cluster with the expectation to use it as High availability.
The license key never came and the HA option was scratched.
Somebody then shutdown that secondary server and reused it for a different purpose without running setup first to properly remove it from the cluster. The installation is AD integrated.
One of the step is probably to delete the publication from SQL.
Anybody knows what to touch in AD and on the remaining server?
