Symptom
The AppleShare client disappears from the Chooser after AppleShare IP or the Mac OS Server Admin application is installed on a computer that has been updated to Mac OS 9.1.
This happens when installing AppleShare IP from disc or when using the Installer for Mac OS Server Admin found on the at the top (root) level of the hard disk.
Solution
Mac OS 9.1 installs a new version (3.8.8) of the AppleShare client extension. AppleShare IP versions 6.3.2 and earlier or the bundled Mac OS Server Admin replaces this new version with an older version (3.8.6) that was current at the time their Installers were created. Subsequently, Mac OS 9.1 disables the older version as incompatible.
You may prevent or address this issue using the approaches described here.
Installing AppleShare IP and Mac OS 9.1 on the same computer
AppleShare IP 6.3.3, announced 2001-01-09 and to be made available in the near future, is required to use Mac OS 9.1 with AppleShare IP. You should not install Mac OS 9.1 on an AppleShare IP 6.3.x server until you have AppleShare IP 6.3.3.
Mac OS 9.1 already installed, AppleShare missing
You may download and install version 3.8.8 of AppleShare from the Apple Software Updates Web site at
http://www.info.apple.com/support/oldersoftwarelist.
Using a Mac OS 9.1 computer as a remote admin station
This does not require AppleShare IP 6.3.3. You may avoid using the Mac OS Server Admin Installer by following these steps:
1. Log on to the AppleShare IP server.
2. Locate the folder named AppleShare IP 6.3 at the top (root) level of the server volume.
3. From there, locate the folder named Mac OS Server Admin.
4. Copy this folder to the Macintosh using Mac OS 9.1.
Once the folder copies, you may begin using Mac OS Server Admin.
