- Change the password in AD Users and Computers as you would normally.
- Log in to the SharePoint Server
- Launch SharePoint Management Shell as an administrator.
- Execute the following:
$newpassword=ConvertTo-SecureString -String “password” -AsPlainText -Force
Set-SPManagedAccount -Identity $username -ExistingPassword $newpassword -UseExistingPassword:$true
- This can take a minute or two to complete. There’s a lot to update here and these changes are intricate.
- Now, open the Windows Server Services control panel on the SharePoint Server machine you are currently logged into, and then sort by the Log On As
- Scroll down until you see the services having the server farm account (eg, spFarm).
- For each of these services:
- 1) verify that it is running;
- 2) if its Startup Type has been changed to Disabled, change it back to Auto;
- 3) if it is not running then start it;
- 4) if on trying to start it, it prompts you for logon information, enter the appropriate logon info, including the new password, and then start it.
- Go back to Central Administration and System Settings > Services on Server.
- Start any service here that should be started but that stopped after you changed the password.
