20000505: Installing MSIE 5 on Classroom Workstations

May/2000
Tech Note #5

There has been considerable interest in Microsoft Internet Explorer version 5 over the past year, and some lab facilitators would like to have it installed (or in some cases may already have installed it) in their Windows 95 labs. Technicians are advised that before installing Internet Explorer 5 on systems which have LockIt95 installed, they should first make sure they have at least rev.1999 of the LockIt95 implementation, and then install the Desktop Update component that was included in Internet Explorer 4. This component is not included in version 5. (See Microsoft Technical Article Q165695.)

LockIt95 (rev.1999 and newer) is compatible with the Desktop Update, and in fact provides better security with the Desktop Update than without it. In particular, the Desktop Update provides the capability to block shell context menus, which are one of the worst security holes we have had to contend with.

So please, if you are upgrading to MSIE 5, install the Desktop Update and the updated LockIt95 first. If you are not certain whether the Desktop Update is installed, simply click on the Start button. If there is a menu item "Log Off [username]...", then it is installed. If there is no "Log Off" item, it is not installed. All Windows 98 systems already have the Desktop Update. If you are not certain if you have the most recent implementation of LockIt95, log on as a locked user. If there are any submenus off the Start Menu other than Programs, you need to upgrade. The upgrade is built in to the latest Anti-Virus Installer: for systems that already have a previous version of LockIt95 installed, running the Anti-Virus Installer is a far more painless way to update LockIt95 than rerunning the installer is.

Note: If a workstation already has MSIE 5 installed, but is missing the Desktop Update, you must uninstall MSIE 5, install the Desktop Update component of MSIE 4, and then reinstall MSIE 5. (See Microsoft Technical Article Q165695.)
