Have you reviewed the task log created for the failed Publisher task and searched for the error in the Qlik Support Portal? Suggest you also review the the QlikView Management Service log for errors/warnings pertaining to the Directory Service Connector service. By default, this log is stored in %ProgramData%\QlikTech\ManagementService\Log and has a naming convention of year_month_day.txt.
If you don't find answers on the portal, provide the errors in this thread with your questions.

Mayuran, my main hunch on this one would be TCP port 4730 is blocked from the Publisher server to the other server running the DSC, can you verify the port is open, you can use the Windows Telnet Client on the Publisher server to try to connect to the port on the other server by doing Telnet DSCServername 4730, and what you should get if things are open is a clearing of the CMD dialog and a blinking cursor in the upper left corner, any error tells you the port is blocked, and you will need to get that opened up. This is the only thing of which I can think if everything shows as online in the QMC etc. and the Windows Services applet shows things are good there.
