PRODUCT :Microsoft Exchange
PROD/VER:5.0

KEYWORDS:kbusage

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

 - Microsoft Exchange Server, version 5.0 
 - Microsoft Internet Information Server 3.0

SYMPTOMS
========

When you connect with Internet Explorer (IE) version 3.01 to Microsoft Exchange
Server, CPU usage jumps up to 100 percent and the browser cannot connect.
Dsamain.exe accounts for between 70 and 80 percent of the CPU use. The browser
is on the same computer as Microsoft Exchange Server and the Internet
Information Server (IIS).

Closing the browser does not help. You have to shut down and restart the
Directory service to continue working.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.0. This problem was corrected in the latest Microsoft Exchange Server
5.0 U.S. Service Pack. For information on obtaining the service pack, query on
