The 7.6 Device Mgr Server Update extension gets installed by ASIP 5.0.2 if the target system is Mac OS 7.6.x. The extension is not installed if the file server has Mac OS 8.0 or 8.1. If Mac OS 7.6.x is then updated to Mac OS 8.x, the 7.6 Device Mgr Server Update extension is not removed during the installation process. This extension also shows as part of the ASIP 5.0.2 package in the Extensions Manager. The functionality of this extension has been rolled into Mac OS 8 and 8.1, therefore you should remove the 7.6 Device Mgr Server Update extension.
