  _____  




The information in this article applies to:

        Microsoft Exchange 2000 Server, versions SP1, SP2



  _____  





SYMPTOMS


When Instant Messaging users try to log on, they may receive the following 
error message: 

Exchange Instant Messaging authentication failure. 
The person logged on to this computer does not have permission to use the 
specified e-mail address. Please supply an e-mail address and logon credentials 
for that address. 


CAUSE


This issue may occur if you have enabled the Require secure channel (SSL) 
option on the Instant Messaging virtual directory in Microsoft Internet 
Information Service (IIS).

Meanwhile, in the W3SVC protocol log that is located in the 
C:\Winnt\System32\Logfiles\W3svc1 folder, you may see the following 403 HTTP 
Response Code entry:

SUBSCRIBE /instmsg/aliases/readec - 403 -) 


RESOLUTION


To resolve this issue, disable Secure Sockets Layer (SSL) on the Instant 
Messaging virtual directory in IIS. To do so, follow these steps on your 
Exchange 2000 server: 

1.      Click Start, point to Programs, point to Administrative Tools, and then 
click Internet Services Manager.


2.      Expand the default Web site, and browse to the Instant Messaging 
virtual directory.


3.      Right-click the Instant Messaging virtual directory, and then click 
Properties.


4.      Click the Directory Security tab.


5.      Click Edit under the Secure Communications section, and then click to 
clear the Require secure channel (SSL) check box.


6.      Click OK twice to close each dialog box.


7.      Stop and then re-start the default Web site in IIS.

Description: The server understood the request, but is refusing to fulfill it. 
Authorization does not help and the request should not be repeated. If the 
request method is not HEAD, the server may make public why the request has not 
been fulfilled. In such a case, the server describes the reason for the refusal 
in the entity. The 403 Response code is commonly used when the server cannot 
reveal exactly why the request has been refused, or when no other response is 
applicable. For additional information about Microsoft Internet Information
