We do have a firewall (Checkpoint FW-1), and Exchange server is in the DMZ
(ie. A true DMZ coming out of a third NIC in the firewall, not MS's
definition).
We are not running proxies though.
I don't think it's a port/firewall/proxy issue because I tried installing
the IM client on the exchange server itself (where IM server is running).
I read about NTLM authentication, I disabled challenge/response in IIS
because I don't want to use reversible encryption on passwords (I did this
AFTER I started having the problem).

The following is a usual problem. Did you check it?
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 AD domain were microsoft.com, you would type
*.microsoft.com.

Hi gurus,
I'm (still) setting up a new Exchange 2k server to migrate our existing 5.5
server. Everything's working fine, BUT IM.
I have created (and recreated around 20 times by now) an IM virtual server,
installed IM client, checked the DNS entries, etc. as per microsoft
step-by-step documentation...
I have installed IM client on the Exchange server itself (to avoid
routing/port/firewall issues). But I keep getting the 'Sign In To Exchange'
dialog box telling me that "The person logged on to this computer does not
have permission to use the specified e-mail address. Please type your
e-mail address and password" asking me for my E-Mail, Username, Password and
Domain.
I'm logged in as myself, and I'm a Schema/Domain/Enterprise admin. I'm
trying to connect using my own IM account.
Any ideas?
Thanks Regards
