High Availability Setup
High Availability refers to the ability of a system or component to limit or avoid disruption when a component fails.

GO!NotifyLink Enterprise Server (GO!NLES) itself is not configurable for High Availability. Therefore, a secondary, or Stand-by, server must be utilized. This server will only be used in the event of the primary server malfunctioning, and should be installed with the exact same hardware specifications as the primary server.
Configuring a Second GO!NotifyLink Enterprise Server
-Install all 3 components on this one server
-Stop all GO!NotifyLink Services, and set them to “manual” startup
-My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Notify Technology Corporation
-As NLES Patches are released and applied to the Active Server, an updated copy of the GO!NLES Directory should be placed on here
Failing over to the Stand-by Server
In the event of a failure on the Web / Messaging component when the Stand-by Server must be activated, the following is a list of steps that should be completed in order to get the NLES Server functioning:
