Disabling The Use of Dr.Web by The Mail Server Manually

In case you encounter problems during the installation or operation of Dr.Web, you can disable the use of plug-in by the mail server:

•If transport agents are installed:

▫In Exchange Management Shell, execute the Get-Transportagent command (if the agents have been installed in transport services, specify them in –TransportService parameter). For detailed information on the command please refer to the website: http://technet.microsoft.com/en-gb/library/bb123536%28v=exchg.150%29.aspx.

▫The agents registered in the specified transport service will be listed in In Exchange Management Shell. For each agent related to Dr.Web (the ones that contain the Dr.Web prefix in their names), copy the name into the Disable-TransportAgent <agent name> command (specify the –TransportService, if necessary). For detailed information on the command please refer to the website: http://technet.microsoft.com/en-gb/library/aa997880%28v=exchg.150%29.aspx.

▫Restart Microsoft Exchange Transport service (and Microsoft Exchange Frontend Transport service, if required). The transport agents will be disconnected from transport services.

▫Re-execute the Get-Transportagent command to make sure that the agents have the Disable status.

The application is now disconnected from the transport pipeline.

•If VSAPI module is installed:

▫Verify the value of the Enabled parameter in [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\VirusScan] registry key: if "Enabled"=dword:00000001, you need to set it to zero: "Enabled"=dword:00000000. If this registry key is missing or the specified parameter is already set to zero, the VSAPI module is already disabled.

▫Restart the Microsoft Exchange Information Store service. The VSAPI module will be disconnected from this service.

The application is now disconnected from the mail stores manager.

•If DrWebSink moduleis installed:

▫Run the command-line tool with administrator rights and execute the following command:

regsvr32 /u "C:\Program Files\DrWeb for Exchange\DrWebSink.dll"

▫Restart Microsoft Internet Information Services (IIS).

Once disconnected from the mail server, the application has no influence on its operation.
