Error code 80040002 is caused by problems with the metabase on a PC connected to a Microsoft Exchange 2000 Server. The IIS metabase can become damaged as the result of hardware problems, System 32 folder scan, or by a disruption from the power source. If the metabase has become corrupt it is necessary to restore the file from the backup system or reinstall the Internet Information Services (IIS) and Microsoft Exchange 2000.

To restore the metabase file from backup you will need to go through the following steps. Click on Start on your toolbar and then choose Programs. Click on Administrative Tools and then choose Internet Services Manager. Choose the name of the PC for Exchange 2000 and then click on Backup/Restore Configuration located on the Action menu.

To reinstall Internet Information Services and Exchange 2000 it is necessary to backup the Mbdata folder which is located on the Exchange 2000 server. When you are ready to reinstall go back to the Metabase.bin file and rename it to Metabase.old. Click on Start on your main toolbar and choose Control Panel from the pop-up menu. Click on Add/Remove Programs and remove IIS and then reinstall it. To reinstall Microsoft Exchange return to Add/Remove Programs and then click on Microsoft Exchange 2000 and then choose Change/Remove.
