7.9 Database utilities
Table 7.8 lists the three utilities you can use to maintain or verify Exchange databases.
| Utility | Purpose | Location |
|---|---|---|
| ESEFILE | Verify checksums of ESE pages | Server CD (see the SUPPORT\UTILS\i386 folder) |
| ISINTEG | Check folders and other application-level structures | Included in Store |

The truth is somewhat different. ESEUTIL can certainly help to get a database running again, but it cannot fix fundamental damage or corruption caused by hardware failure. In these circumstances, if you encounter a series of 1018, 1019, or 1022 errors in the event log, the best procedure is to restore the database from the last good backup and roll forward all subsequent transactions by replaying the transaction logs.
ISINTEG verifies the application-level structures (tables and pointers), but it depends on a good database. Thus, if ESEUTIL cannot fix the problems in a database, ISINTEG will not be able to work any magic either.
7.9.1 Running ESEUTIL
ESEUTIL has no knowledge of database contents and operates on a page level in different modes. When recovering from a database problem, the two most important modes are /D (defragmentation) and /P (repair). Always take a file-level backup of a database before you begin working with ESEUTIL. Only use the version of ESEUTIL compatible with...
