SYMPTOMS
When you configure the Microsoft Internet Security and Acceleration (ISA) Server 2000 Simple Mail Transfer Protocol (SMTP) Message Screener, a message that contains keywords that you have screened may still be delivered to the Inetpub\Drop folder on the SMTP virtual server.



CAUSE
This behavior occurs if both of the following are true:
 * You install ISA Server 2000 on a Microsoft Windows Server 2003-based computer.
 * The ISA Server is installed as a standalone ISA Server.
 * The SMTP message screener is installed on the SMTP service that is running on another computer on the local area network (LAN).

This issue occurs because the Message Screener cannot read the SMTP Filter configuration information from the ISA Server 2000 computer. Because of this, the message filtering does not work, and all messages are passed.



RESOLUTION
To resolve this issue, install the ISA Server 2000 Required Updates for Windows Server 2003. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Microsoft Internet Security and Acceleration Server 2000.
