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:
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.
