Launch the Java Management Console
Enter in a DNS or IP address in the 'Server Address' field
Under the 'User Name' field enter something similar to the following: cn=Administrator,cn=Users,dc=lab,dc=novell,dc=com
Be sure the port is either 1389 or 1636 (and 'Use SSL' is checked) depending upon your eDirectory ldap settings. If port 636 is used, then the DNSDHCP and/or dhcpLocator objects will not be found.
As always, backup the DNS configuration before doing any additions or modifications. This is particularly important on a DSfW server.
