Common Installation ProblemsThere are several common problems that can come up during the setup process, generally relating tonetwork or naming problems. These problems and workarounds and solutions are described below.For system information, try running the dsktune utility to identify potential hardware problems.7.7.2.1. Problem: Clients cannot locate the serverSolution.First, modify the hostname. If that does not work, use the fully-qualified domain name, likewww.domain.com, and make sure the server is listed in the DNS. If that does not work, check the IPaddress.If the NIS domain is not the same as your DNS domain, check your fully-qualified host and domainname.7.7.2.2. Problem: The port is in useWhen setting up a Directory Server instance, you receive an error that the port is in use. This is verycommon when upgrading or migrating an existing server.SolutionThis error means that you did not shut down the existing server before beginning the upgrade ormigration. Shut down the existing server, and then restart the upgrade process.If this occurs during a setup process, it may mean another server is already using this port. Verify thatthe port you selected is not in use by another server.7.7.2.3. Problem: Forgotten Directory Manager DN and passwordSolution.By default, the Directory Manager DN is cn=Directory Manager. If you forget the DirectoryManager DN, you can determine it by checking the nsslapd-rootdn attribute in the dse.ldif file,in the /etc/dirsrv/slapd-instance_name directory.
