It might have not cleared the .lock file so the Admin Tools Service didn’t start.
Try deleting the .lock file and then reboot.
To get more details about what the issue is, find your oe102_wrk folder and look at the admserv.log file
// Your oe102a_wrk might be located somewhere else
C:\Epicor\oe102a_wrk\admserv.log
Assuming its your .lock file - you should see an error like:
Adminserver lock file exists and process still running. Lock: C:\epicor\OEManage\config\admsvr.lock PID: 2208 (11363)
Shutting down adminserver, lock file found. (11356)
Just go to C:\epicor\OEManage\config and delete the .lock file, and restart. If that is not it, then continue investigating the admserv.log for other issues.
