If you try to kill the process from task manager, it failed with Access Denied error, I have used schedule task to run the batch file (batch file uses the repadmin command) schedule task failed with could not start, because the repadmin command stuck in task manager
I have used task manager to end the repadmin process, and used taskkill / pskill tools to kill the process without success, always failed with Access denied file used by another process
I have used pskill tool from remote server, finally it’s resolved
PSKILL \\server name process ID
Process ID can be get through the tasklist / pslist command.
Good information guys
