XADM: A Cluster Registry Checkpoint Event ID 1024 Error Message Is Logged (316772)


The information in this article applies to:

  • Microsoft Exchange Server 5.5
  • Microsoft Windows NT Server, Enterprise Edition 4.0
This article was previously published under Q316772

SYMPTOMS

If an Exchange Server 5.5 computer is running in a Windows NT Server 4.0 cluster, an error message may be logged in the System event log that is similar to:
Event ID: 1024
Source: ClusSvc
Type: Error
Category: (64)
Description: The registry checkpoint for cluster resource Microsoft Exchange Internet Mail Service could not be restored to registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIMC. The resource may not function correctly. Make sure that no other processes have open handles to registry keys in this registry subtree.

CAUSE

This issue may occur if the registry key for that resource is being used. The Winlogon.exe locks the following registry keys:
  • HKEY_LOCAL_MACHINE\System\ControlSet001\Services\MSExchangeIMC\Diagnostics
  • HKEY_LOCAL_MACHINE\System\ControlSet001\Services\MSExchangeIS\ParametersSystem
  • HKEY_LOCAL_MACHINE\System\ControlSet001\Services\MSExchangeIMC\Parameters
Even after you quit the Exchange Server Administrator program, Winlogon keeps these registry keys locked. Therefore, when you take the cluster offline, and then bring it online again, Exchange Server cannot write the registry checkpoint because Winlogon has the keys locked.
