Cannot Access OpenLDAP Directory Server for Windows

Question

Hi All,
Need urgent help for connecting to LDAP server which I installed on my Win 2000 Professional m/c. The LDAP installation was downloaded from the site www.ilex.fr/openldap. I successfully installed it. In the slapd.conf file, I have set the server suffice as dc=mycompany,dc=com and the rootdn is cn=Manager,dc-mycompany,dc=com. I have the following piece of code which tries to list the Java schema in the LDAP directory. The code was downloaded from sun's JNDI tutorial. The name of the Program is
CreateJavaSchema and it is run by giving the following options:
-l     List the Java schema in the directory
-n<dn>      Use <dn> as the distinguished name for authentication
-p<passwd>     Use <passwd> as the password for authentication
-a<auth>     Use <auth> as the authentication mechanism. Default is "simple".
I tried to run the program as java CreateJavaSchema -ncn=Manager,dc=mycompany,dc=com -psecret99
where secret99 is the root password . However I get the following exception
javax.naming.CommunicationException: localhost:389. Root exception is java.net.ConnectException: Connection refused: connect
Can somone help me with this?
Thanks

The Code ..yes
Here it is: .This code is availbale from JNDI tutorial. I run the program by specifying following command-line arguments.
java ListJavaSchema -ncn=Manager,dc=mycompany,dc=com -psecret99.
However I get the exception "javax.naming.CommunicationException: localhost:389. Root exception is java.net.ConnectException: Connection refused: connect"
