Symptom
After updating to ARD 1.2 at your administration computer, you cannot administer ARD 1.1 client computers that use Mac OS 9.
Solution
If you have not yet updated any of your ARD software to version 1.2, you may avoid this issue by updating the client computers first. If you have already updated the administration computer first, there are two alternatives: You may either update the client computers locally, or you may reinstall ARD 1.1 at the administration computer.
I. Locally updating clients
This method may be easier if you have only a few affected ARD client computers. You may individually update each computer to ARD 1.2 by using the Software Update control panel or by using the standalone installer available from software download document 120206, "
Apple Remote Desktop 1.2 Client for OS 8.1 - 9.2: Information and Download".
II. Reinstalling ARD 1.1
This method is easier when you have many affected ARD client computers. Follow these steps:
1. At the administration computer, uninstall ARD 1.2. To do this, see technical document 107159, "Apple Remote Desktop: How to Uninstall".
Note: If there is a secondary Mac OS X computer that does not already have ARD administration software installed but on which you would not mind having it installed, then you may continue to Step 2 at that computer without completing Step 1.
2. If you have the ARD 1.1 CD, reinstall the ARD 1.1 administration software. If you have the ARD 1.0 CD, please contact AppleCare Technical Support for assistance with installing ARD 1.1.
Note: If prompted to update, be sure not to update to version 1.2.
3. Download the update from software download document 120206, "Apple Remote Desktop 1.2 Client for OS 8.1 - 9.2: Information and Download".
4. On the update disk image, look in the Remote Desktop Parts folder and locate the Remote Desktop Startup extension.
5. Open the ARD 1.1 application.
6. Select the affected client computers from the Computer Status list.
7. Copy the Remote Desktop Startup extension to the selected computers, with a destination of:
System Folder: Extensions
8. Restart the selected client computers.
9. Update the administration software to version 1.2, using the Software Update pane of the System Preferences application.
