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. -----Original Message----- From: Andrea Coppini [mailto:AndreaCoppini@xxxxxxxx] Sent: Lunes, 26 de Agosto de 2002 05:27 p.m. To: [ExchangeList] Subject: [exchangelist] IM not connecting http://www.MSExchange.org/ 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?
