SYMPTOMS
After you apply Internet Security and Acceleration (ISA) Server Service Pack 1 (SP1), you may receive the following events:

Type    : Error Source  : SmtpEvt Catagory : None Event ID : 20031 Message : &quot; An unknown SMTP command &quot;

OR

Type    : Error Source  : SmtpEvt Catagory : None Event ID : 20033 Message : &quot; The SMTP command exceeded its allowed length &quot;



CAUSE
After the ISA Server SMTP filter is updated by ISA Server 2000 SP1, event ID 17220 and 17240 are changed to 20031 and 20033. Because of this, you cannot correctly view the 17220 and 17240 events in the Application Log after you apply ISA Server 2000 SP1. Instead, you receive a &quot;The description for Event ID (x) in Source (Y) cannot be found&quot; message.



STATUS
This behavior is by design.



MORE INFORMATION
SmtpEvt 20031 or 17220 - An Unknown SMTP command

This message is logged when the SMTP Filter service in ISA Server receives a command that is not listed under the SMTP Commands tab in the SMTP Filter properties. The command that was passed appears in the DATA section of the event message. If the command was expected, you must add this command to the SMTP Filter properties SMTP Commands tab.

SmtpEvt 20033 or 17240 - The SMTP command exceeded its allowed length

This message is logged when the SMTP Filter service in ISA Server receives a command that is longer than the permitted length that is listed under the SMTP Commands tab in the SMTP Filter properties. The command that was passed appears in the DATA section of the event message. If the command was expected, you must modify the permitted length of this command in the SMTP Filter properties SMTP Commands tab.
