Remove Trend registry keys and restart Microsoft Exchange Information Store. Perform the following steps on each server in the cluster:
1. Remove the following registry keys.
WARNING: Symantec strongly recommends that you back up the registry before you make any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the keys that are specified. Read the document How to back up the Windows registry for instructions.
HKLM\SYSTEM\ControlSet001\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanBackgroundScanning
HKLM\SYSTEM\ControlSet001\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanEnabled
HKLM\SYSTEM\ControlSet001\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanProactiveScanning
HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanBackgroundScanning
HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanEnabled
HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<EVS Name>
\Private-xxxxxxxx\VirusScanProactiveScanning
2. Restart Microsoft Exchange Information Store.
Note: Rather than restart the information store the VSAPI registry key can be set. After this is set Exchange reloads SMSMSE and sets the registry key to zero.
a. To reload VSAPI set the registry key "HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\Virusscan\Reloadnow" to 1.
