Few things to check: 1. Make sure you add the entries in both the Services file manually. 2. Make sure the dbinit file is modified after creating the service and before starting it. (Step 7 in the link I referred)
** Also go to the the SDE Home--> etc folder and check the error in the sde_logfile (sde_newdrumisd). Maybe that would give us more information.
If this still doesn't help, my suggestion would be to contact the ESRI Tech Support for better troubleshooting.
