Have you set a client to NTLM Auth on an off-domain computer? Does it simply prompt for login and still work, or does it kick back an error of some sort?
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Simon Butler Sent: Tuesday, February 22, 2005 4:45 PM To: Exchange Discussions Subject: RE: Exchange over HTTP and NTLM Auth I have always set mine to use NTLM authentication. This has eased the implementation of RPC/HTTPS as the users don't even notice that anything has changed - until they forget to start the VPN and get their email! Even my computer at home (on my home domain) is using NTLM. It simply prompts me for username and password details. Therefore with your domain machines, use NTLM. If they are using a non-domain computer then they will get prompted each time - and there is no way of saving the password. If they do get a prompt then there is a small change you can make to the authentication process to fix that. If you want to check that Outlook is connecting over RPC/HTTPS, close Outlook completely, using task manager to make sure that outlook.exe has gone. Then click start, run and type Outlook.exe /rpcdiag This will show exactly what is going on. I have screenshots of a working and non-working installation on my web site at http://www.amset.info/exchange/rpc-http-diag.asp Simon. -- Simon Butler, MCP, MCSA Senior Systems Administrator Amset IT Solutions Ltd. e: simon @ amset-it.com w: www.amset-it.com w: www.amset.info -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Evan Mann Sent: 22 February 2005 19:56 To: Exchange Discussions Subject: Exchange over HTTP and NTLM Auth All of the documentation I have read for Exchange over HTTP indicates that Basic Authentication should be used. This requires you to login to outlook to authenticate to the Exchange 2003 Server. In some testing, I've set a computer joined to the domain to use NTLM Authentication and Outlook opens without a login request. Everything looks as though an Exchange over HTTP connection is used and not a direct RPC connection. I have not tested this on an off domain computer. Is there some reason that Basic Authentication is always referenced or can NTLM Authenticatiob be used? Can it only be used with domain computers or both domain and off domain computers? I'd like to remove my users requirement to login wherever possible. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
