Symptom
When you set up email notifications for Server Monitor in Mac OS X Server 10.2, if you delete all the email addresses from the "To" field, you are unable to add any new addresses. Clicking the Add button does not add a new addresses.
Solution
1. Quit Server Monitor. If more than one instance of Server Monitor is connected (local and remote), be sure to quit them all.
2. Delete these files from the server:- /Library/Preferences/Server Monitor Prefs
- /etc/hwmond.conf
Notes
1. Deleting these files will remove all customized settings in Server Monitor. After deleting these files, you must add your server to the list again.
2. When Server Monitor is used on a remote system, there is a local preference file that must be updated after deleting the files on the server. To update the preference file on the remote system, open Server Monitor and select Edit Notifications for the affected server. You now should be able to successfully add a new email address. If you cannot add new addresses, delete the following file on the remote workstation while Server Monitor is not open:
/Library/Preferences/Server Monitor Prefs
