This article discusses an update that lets you create a dump file of the Microsoft Exchange 2000 Server information store on a server cluster if the IsAlive function cannot communicate with a particular resource.
Note The configuration steps in this article apply to Microsoft Exchange Server 2003 and Exchange 2000. The hotfix is only required for Exchange 2000. No hotfix is required to configure DumpProcessOnIsAliveFailure on Exchange 2003.
On a server cluster, the IsAlive function communicates with the cluster resources to determine if those resources are functioning correctly. If a particular resource does not respond, you might want to immediately dump the information store to help you determine why that resource did not respond.

Hotfix installation informationAfter you install this hotfix, when IsAlive fails because of either a timeout or an error from the IsAlive check, the Exres component determines if the failed cluster resource has the private property DumpProcessOnIsAliveFailure set to a non-zero DWORD value. If this property is set to a non-zero value, Exres calls the existing functionality in Exchange to dump the information store. The function to dump the information store requires the following registry subkey to be set:
To configure these settings, follow these steps:
