MORE INFORMATION
Exchange Server 5.5
The information in this section applies to all three Exchange Server 5.5 databases: • Dir.edb
• Priv.edb
• Pub.edb
To display the Edb.chk (checkpoint) file on the screen, run the following command from a command prompt:
eseutil /mk edb.chk | more
If you do not run eseutil from the folder where the Edb.chk file is located, you must provide the full path to the file.
In Exchange Server 5.5, there is one checkpoint file for each set of log files. There will be one Edb.chk file for the directory and one for the information store. (Priv.edb and Pub.edb share the same log files and checkpoint file.)
The information that is displayed is similar to: Microsoft(R) Exchange Server Database Utilities
Version 5.5
Copyright (C) Microsoft Corporation 1991-1997. All Rights Reserved.
Take the first number in the parentheses for the Checkpoint field and convert it to hexadecimal. The hexadecimal number is the file name of the first uncommitted log for the appropriate directory. Circular logging works by deleting all log files with generations that are lower than the generation in the checkpoint, for example:
Checkpoint (22,6485,399) = EDB00016.LOG
This syntax applies for most other fields in the dump file (LastFullBackupCheckpoint, FullBackup, IncBackup, and other fields).

Exchange 2000 Server
In Exchange 2000, there is one checkpoint file for each storage group and one for the directory. When you try to identify the last committed log file for a storage group, note that the storage group prefix applies to the checkpoint file and to all of the log files. For example, the default first storage group's checkpoint file name is E00.chk, and its log files are E00xxxxxx.log (where xxxxx is the hexadecimal sequence number of the log file).
To display the Exx.chk (checkpoint) file on the screen, run the following command from a command prompt (from the Exchsrvr\Bin folder):
eseutil /mk the_full_path_to_the_checkpoint_file
For example, you may run the following command:
eseutil /mk "C:\Program Files\Exchsrvr\MDBDATA\E00.chk"
Note that you must use the quotation marks if there is a space in the path to the checkpoint file.
The output of this command is similar to: Microsoft(R) Exchange Server(TM) Database Utilities

Operation completed successfully in 1.192 seconds.
Take the first number in the parentheses for the Checkpoint field. The hexadecimal number is the file name of the first uncommitted log for the appropriate database; in this example:
Checkpoint (0x6A,1119,3D) = E000006A.log
