Check this:
If your organization uses a firewall or proxy server, NTLM authentication may 
not be working. The Instant Messaging client uses Microsoft Internet Explorer 
proxy settings, so you must add your Instant Messaging domain to the Internet 
Explorer Exceptions list. To modify the Exceptions list: 

1.      In Microsoft Internet Explorer 5 and later, click Internet Options on 
the Tools menu. In Microsoft Internet Explorer 4.x, click Internet Options on 
the View menu.

2.      Click the Connections tab.

3.      Click the LAN Settings button.

4.      Click the Advanced button in the Local Area Network (LAN) Settings 
dialog box.

5.      In the Exceptions box, under Do not use proxy server for addresses 
beginning with, type your domain name preceded by an asterisk (*). For example, 
if your domain were, you would type *

I've installed IM on one of the Exchange 2000 servers.

I have verified all the settings with Exchange 2000 documentation and it seems 

I couldn't see any events related to IM in server's application logs.

I'm receiving below error on w3svc log file on server.
