A user with the same name exists.
In a multiple NetWare server environment, it is common to find duplicate user and group accounts entered in the binderies of more than one server. This is because every server on a NetWare network has its own account database.
In the User and Group Options dialog box, click the Group Name tab and select one of the following three options to handle duplicate user names: 1. Log Error: This is the default option. If duplicate user accounts exists, the information will be added to the ERROR.LOG file when the NetWare server is migrated to the Windows 2000 domain. Use this option on the Trial Run to find conflicts with the migration process. 2. Ignore: Will cause no action to take place. Duplicates will be ignored. 3. Overwrite with New Info: This option will overwrite existing account information on the Windows 2000 domain with the duplicate user name information that is being migrated from the NetWare server. If you choose this option, the password, user rights, and permissions of the existing account on the Windows 2000 domain will be over-written with the user account properties set for the user that is being migrated from the NetWare server. 4. Add Prefix: Will create a new Windows 2000 account when duplicate user and group names occur.
