Log in to the application server hosting the Console as the Carbon Black Service Account.
Update the App Control Services (services.msc)
Stop the following services:
App Control Reporter Service
App Control Server Service
For each: Right click > Properties > Log On
Enter the updated credentials and click OK.
Open IIS Manager > expand the server name > select Application Pools:
Right click DefaultAppPool > Advanced Settings > Process Model > edit the Identity > update the password
If the Identity account is set to "ApplicationPoolIdentity" NO change is needed.
Server 8.10.2+: Right click AppCDownloads > Advanced Settings > Process Model > edit the Identity > update the password
If the Identity account is set to "ApplicationPoolIdentity" NO change is needed.
Close IIS Manager and restart the webserver (run the "iisreset" command from an administrative command prompt)
Start the services from Step 3.
Additional Information
In some instances the temporary files in "C:\Users\SERVICEACCOUNT\AppData\Local\Temp" will need to be deleted after the password update is complete, and while the services are stopped.
If you have an App Control Agent installed, but do not know the Global CLI Password you will need to make the changes to the Services & IIS Identity via Safe Mode.
