Event Id1124
DescriptionThe consistency checker encountered an internal error and cant continue checking the consistency of this directory. Stop and restart this Microsoft Exchange Server computer.
Event InformationAccording to Microsoft:
The following registry entries do not contain the correct Organization, Site, or Server Name, respectively:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA \Parameters\Enterprise
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA \Parameters\Site
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA \Parameters\Server
To work around this behavior, change the registry entries to match the correct Organization, Site, and Server Names specified in the Microsoft Exchange Directory and restart the server. To verify the correct Directory Name for the Organization, Site, and Server, run the Microsoft Exchange Administrator program in Raw Mode and note the "Directory-Name" attribute in Raw Properties for each of the three objects.
