XADM: Error -530 Occurs When Starting the Directory or Information Store Service

ID: Q160024

The information in this article applies to:

Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SYMPTOMS

When you try to start the Microsoft Exchange Server Directory or Information Store service, the service does not start. The Event Viewer indicates that the service returned an error -530.

CAUSE

Error 530 refers to the Jet error : JET_errBadLogSignature. This indicates a problem with one or more log files.

RESOLUTION

To resolve this problem, do one of the following:

If the case the Directory Service is not starting:

Move all the .log and .chk files out of the Exchsrvr\Dsadata directory

Run edbutil /r /ds to regenerate the log and check files, and then try to start the service again.

If the Information Store service is not starting:

Move all the .log and .chk files out of the Exchsrvr\Mdbdata directory

Run edbutil /r /is to regenerate the log and check files, and then try to start the service again.

NOTE: The Dsadata and/or Mdbdata subdirectories that contain the .log files may be on different drives, depending on whether the Performance Optimizer or Administrator program has been used to move the database files. Moving the .log files out of the corresponding directory may cause the service to start, but any unflushed data in the .log files will not be written to the Exchange Server database and will be lost. While the service (Directory or Information Store) is running, any changes are first written to the .log file and then periodically flushed out to the Exchange Server database. When the Exchange Server service is properly shut down, all data is written to the corresponding Exchange Server database.
