Product Requirements

(Server Components)

All servers within a cluster should be running the same version of Windows. See Certification Information

LifeKeeper for Windows only supports 64-bit platforms (excluding x64 and Itanium). If you are using LifeKeeper for Windows on a system running Microsoft FTP Service 7.5 for IIS 7.0, Windows Server 2016 or later is required.

Note: While installing LifeKeeper for Windows on Windows 2016, a dialog box will prompt whether the installer should make the system configuration changes described below. If the installer is not allowed to make these changes, they will need to be made manually after installation is complete.

• Windows Firewall
• The Distributed Link Tracking Client must be disabled

For systems running LifeKeeper for Windows and Microsoft FTP Service 7.5 for IIS 7.0, Windows 2016 or later is required.

In addition, if your Windows servers are not in a domain, the Local Security policy setting “Network Access: Let Everyone permissions apply to anonymous users” must be enabled. If the servers are in a domain, then this setting is not required.

(User Interface)

LifeKeeper for Windows uses Port 82 for Remote Method Invocation (RMI) communication between the GUI server and client.

The LifeKeeper GUI uses Port 81 for its administration web server which should be different from any public web server. This is used by the GUI when run as a Java applet on a remote client.

In the event of conflict with an existing application, these ports can be changed by editing the RMI_PORT or WEB_PORT entries in the SIOS\LIFEKEEPER\JAVAGUI\SERVER registry key.
