iSQL *Plus Application Server service error

I am on Windows Server 2003 SE and using Oracle 10g (10.1.2). The iSQL Plus Application Server service and listenser service both are automatic on startup. But during the start up iSQL*Plus Application Server doesnt start and it throws an error. It says it couldnt start this service and "Error 1067 the process terminated unexpectedly"

Everything was goin smooth but after a re-boot, all of sudden this service failed to start. Can any1 help me out ? Received on Wed Feb 07 2007 - 02:54:23 CST
