The Microsoft® Exchange Server Analyzer Tool queries both the cluster registry (HKEY_LOCAL_MACHINE\Cluster) and the Active Directory® directory service to determine if the paths for Exchange data files (for example, message tracking log files) are the same in both places. Exchange Server configures these values in the registry and in Active Directory when the Exchange Setup program is used to install Exchange on a node in a Microsoft Windows® server cluster.

The registry value created by Exchange Setup and read by the Exchange Server Analyzer is:

HKLM\Cluster\Resources\<Resource GUID of Information Store resource>\Parameters\DestPath

The Active Directory value created by Exchange Setup and read by the Exchange Server Analyzer is: msExchDataPath. This value is an attribute of the Exchange Server computer object in Active Directory, which is found at:

CN=Configuration, CN=Services, CN=Microsoft Exchange, CN= OrganizationName =Administrative Groups, CN= AdministrativeGroupName , CN=Servers, CN= ServerName

If the Exchange Server Analyzer finds that the values for DestPath and msExchDataPath do not match, an error is displayed.

A common cause for these values to be different is when the location of some or all Exchange data files changes after Exchange has been in production. For example, if hardware is upgraded, message tracking log files are moved, and a drive letter is changed, the change is reflected in the cluster registry but not in Active Directory. After such a change has been made, service startup errors, database mounting issues, and other problems may result, especially when applying an Exchange service pack or installing a roll-up package.

You should resolve this discrepancy as soon as possible. Do not install any service packs or updates to Exchange Server until this problem is corrected.

To perform the following procedure, you will need to use an Active Directory editor such as Active Directory Service Interfaces (ADSI) Edit or the LDP (ldp.exe) tool.

If you incorrectly modify the attributes of Active Directory objects when you use ADSI Edit, the LDP tool, or another Lightweight Directory Access Protocol (LDAP) version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server™ 2003, Exchange Server 2003, or both. Modify Active Directory object attributes at your own risk.

To correct this error

  1. Modify the affected Exchange Virtual Server (EVS) value for msExchDataPath so that it matches the value in the cluster registry for DestPath. The msExchDataPath attribute can be found at: CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=OrganizationName=Administrative Groups, CN=AdministrativeGroupName, CN=Servers, CN=ServerName

  2. Restart the virtual server's Exchange System Attendant resource for the change to take effect.
