Error uninstalling Exchange 2013

Hey all,

I got an error uninstalling Exchange 2013 from Server 2012 (because of course I did, it's Exchange!).

All mailboxes have been removed, DAG has been decommissioned, I've had it in maintenance mode to ensure that nothing is using it.  I was using the following guide (and consulting other sites as well).

Decommissioning Exchange Server 2013 - Microsoft Tech Community

I ran Setup.exe /mode:Uninstall from the Exchange\v15\bin directory.  Here is the result:

C:\Program Files\Microsoft\Exchange Server\V15\Bin>Setup.exe /mode:Uninstall

I can see that the MSExchangeTransport service is in the Stopping state.  Seeing as Exchange is what it is, I want to be sure of the troubleshooting steps.

Do I just reboot and try the uninstall again?  Should I try set this service to not start at startup before rebooting?  Is there some other advisable step to do?

thanks
