This procedure will work on Workgroup Servers and other Macintosh computers running AppleShare IP. This will not cure issues due to a damaged Users & Groups Data File or AppleShare PDS file. This is the procedure to use if your system software on a Mac OS AppleShare server has become unusable, and you want to replace it while preserving privileges and sharing information.
Note: Before proceeding with Step 1, ensure that you have a backup of your file server that can be used for recovery purposes. Many times, backup servers may be used to test the quality of a file server backup to ensure recoverability.
To backup your file server properly, the AppleShare server software must be active to retain users, groups, permissions and sharepoints.
If you are installing Mac OS 7.6 or 7.6.1
After the clean installation is complete, install any supported Mac OS Updates.
When the installation is finished, restart the computer normally so that it restarts from the hard drive. If you get a dialog box from the Energy Saver Control panel, be sure to set the preferences to never spin down the hard drive or put the computer to sleep.
If you are installing 7.6, open the Sharing Setup control panel and fill out the Owner Name, the Owner Password, and the Machine name. Make careful note of the exact Owner Name and Owner Password you enter. Later on these will be the AppleShare Administrator name and password.
The Mac OS Setup Assistant should launch when you start up. Complete that. Make careful note of your answers to the questions "What is your Name" and "What password would you like to use on your computer?" Later, this will be the AppleShare Administrator name and password. When the setup assistant asks you if you want to share a folder on this computer, select "No."
Open the System Folder, and inside the System Folder open the Preferences folder. Drag the Users & Groups Data File to the Trash. Close the Preferences folder.
Locate the folder named Previous System Folder and open it, then open the Preferences folder. While pressing and holding the Option key on your keyboard, drag the Users & Groups Data File to the desktop. (Holding down the Option key will let you copy the Users & Groups Data File instead of moving it.) Close the Preferences folder and the Previous System Folder.
The System Folder should still be open (if it is not, open it). Drag the Users & Groups Data File from the desktop to the Preferences folder of the open System Folder.
Restart and install AppleShare IP Software. Be sure to install any necessary updates prior to launching the AppleShare IP Easy Setup. Restart the computer.
Run AppleShare IP Easy Setup. It should detect your serial number from the previous Users & Groups Data File. Once you finish walking through Easy Setup, your server should be running with the previous user list and access privileges.
