When you use Innoculan anti-virus software on a Windows NT Server version 4.0 Service Pack 3 (SP3) computer running Microsoft Exchange Server, the Exchange Directory (DS) service will not start. In the Windows NT Event Viewer Application log, you will see the following error:

Unexpected NT API error: 0xC000000D
MSExchange DS ((153) ) - 1022
Error -1022 has occurred (internal ID 2030149). Contact Microsoft
Technical Support for assistance.
The Microsoft Exchange Server database (EDB) could not be initialized
and returned error -1022. Unrecoverable error, the directory can't

This is because Innoculan installs a file system filter that disables the JET engine ESE97, from addressing database files.


One of the two following workarounds may be used if Innoculan is installed on the Exchange Server.

  1. Uninstall Innoculan and restart the computer. Disabling the Innoculan service is not sufficient.
  2. Install a Windows NT hotfix that been released to customers as part of the roll-up hotfixes that are recommended in the readme.doc file for Microsoft Exchange Server, version 5.5. These hotfixes are available at:

Note: If you later re-install Windows NT Service Packs, you must also re-install the hotfixes regardless of your responses to the Overwrite Newer Files prompts during the Service Pack installation.


This same error has occured with Norton NT Tools version 1.0 installed. Disabling the Norton service does not work, it must be removed.

Omtool Fax Senior 2.5 will produce this error with an internal ID of 2030148. The hotfix noted above also corrects this problem.
