i have installed SQL server 2005
but i had a warning message while try to start the SQLSERVERAGENT service
"SQLServerAgent service on local computer started and then stopped. some services stop automatically if they have no work to do, for example the performance logs and alerts services"
And also i don't have the SQLAGENT.OUT file in the following path: C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG
Please help me to start the SQLSERVERAGENT service
