Article: Q194787
Product(s): Internet Information Server
Version(s): WINNT:4.0

Keyword(s): kbWinNT400sp4fix

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Internet Information Server 4.0

SYMPTOMS
========

The SMTP service included with Internet Information Server 4.0 rejects messages
when the HELO or EHLO command times out. When the SMTP service tries to deliver
a message and times out while waiting for the response to the HELO or EHLO
command, an NDR is generated and no further retries are attempted.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or
Windows NT Server 4.0, Terminal Server Edition. For additional information,
please see the following article in the Microsoft Knowledge Base:
