When you start the Microsoft Exchange Directory service (DS), you might receive the following error:

Error 2140. Internal Windows NT error.

and you will find the following Event ID in the Windows NT Event Viewer Application log:   Event ID: 1002 Source: MSExchangeDS Type: Error Category: Internal Processing Description: The Microsoft Exchange Server database, EDB, could not be initialized and returned error -1022. Unrecoverable error. The directory cannot continue.



RESOLUTION
Error -1022 corresponds to JET_errDiskIO. There are three steps you can take to resolve this problem:

 Run CHKDSK to verify that there are no problems on the hard disk drive. Check permissions on the EXCHSRVR\DSADATA directory. The Microsoft Exchange Service Account must have Full access to this directory. Verify that you are not receiving virtual memory errors when booting the computer. The following error may be displayed on startup.

Limited Virtual Memory

Your system is running without a properly sized paging file.

Please use the virtual memory option of the System applet in the

Control Panel to create a paging file, or to increase the initial

size of your paging file.
