problem in starting TNSListner

[michell o'brien]

I am not able to start my TNS Listner. When I start from the services I get this error.

The OracleDB11g_home1TNSListner service on Local computer started and then stopped.
Some services stop automatically if they are not in use by other services or programs

When I try to start the listner from command prompt I get this message

D:\>lsnrctl start
