I have an old exchange 2003 server. I uninstalled exchange several weeks ago. It has not run exchange since I migrated to exchange 2010 a few months ago. The server has been powered down for at least the last three weeks when I uninstalled exchange 2003, and it was also powered off for a couple of weeks after the migration a few months ago to make sure everything with email worked before decommissioning it entirely.
So, had the time and gumption to decommission today. powered it on, went to unjoin and it's grayed out stating:
The identification of the computer cannot be changed because :
- The Certificate Authority Service is installed on this computer"
we've not had any issues at any point while the machine is powered off. I am not certain how to proceed. any suggestions much appreciated.
