If this happens, restart the NMAS server installation. When the dialog box appears again, you need to manually shut down eDirectory. Do this by going into Control Panel and clicking eDirectory. Highlight the ds.dlm file (Novell Directory Services) and click Stop. After the directory services have been stopped, you can return to the dialog box, click OK, and the installation will continue properly.
Symptom: When you launch the install again, the "NMAS Server Components" check box is dimmed and not selectable.
Solution: Kill the launch.exe process. This can be done by pressing Ctrl+Alt+Delete and selecting Task List. On the Processes tab, select launch.exe, then click End Process.
