The massage server starts but the dispatcher doesn't start in sap

Symptoms :
The dispatcher shows status "Stopped" in sap mmc
The dev_disp file shows errors
***LOG QOA =>nisertono,service_unknown(sapdp00)(nixxi.c2580)
***ERROR =>DpCommInit :Dpxxdisp.c 7326)
***DP_FATAL_ERROR=>DpSapEnvInit:DpCommInit
*******DISPATCHER EMERGENCY SHUTDOWN********\

Cause of problem :
The Keyword in the massages above is servicce_unknown followed by the entry name"sapdp00"The dispatcher entry "sapdp00"is missing in the services file ex sapdp00 3200/tcp

How to resolve:
Add the necessary entry in the services file  EX: sapdp00 3200/TCP then Re-start the instance
