Follow the steps in this document to remove managed settings from your computer that persist after visiting a network on which clients are managed. This article applies to Mac OS X Server 10.2, 10.3. For information about Mac OS X Server 10.4, see this article.
To remove the managed settings, follow these steps:
1. If have not already done so, disconnect the Ethernet cable from the computer's Ethernet port, or turn off AirPort from the AirPort menu bar item, or do both. This removes the computer from the network on which Workgroup Manager is active.
2. Log in to the affected computer as an Admin user.
Note: If you are the network administrator, this refers to the computer's local Admin user, not to the server's.
3. At the Workgroup Picker dialog, click the Refresh Preferences button.
Note: If the Workgroup Picker does not appear after logging in, you must log out. You may then force the Workgroup Picker to appear by pressing the Shift key as you click the Log In button.
This will remove the cached settings.
If you skip step 1, you may temporarily clear the cached settings while still connected to the network. The settings will be re-cached when logging out or when clicking the Go Back button in the Workgroup Picker.
