You may want to check their RPC binding order if you haven't done so. http://support.microsoft.com/default.aspx?scid=KB;EN-US;q163576&

I am not convinced it is a name resolution issue anyway because it only effects a small number of users across multiple subnets and Exchange servers, while the vast majority of users have no problem.

Outlook is a NetBIOS type of animal. Have you tweaked the Provider order in the registry of your clients to match the network protocol used on your network? -----Original Message----- From: Bendall, Paul [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 10, 2002 8:59 AM To: Exchange Discussions Subject: MAPI/Outlook detailed logon process Hi all, Exch 5.5, SP4, post-SP4 hotfixes, Windows 2000 SP2 and Windows NT 4 SP6A I hope someone can help, does anyone know of a whitepaper that documents in detail the Outlook logon process? I want to know the order things are done, i.e. names resolution occurs first using DNS by default, then RPC connections to the Exchange server, then what happens when is the security token checked against the mailbox, how does Outlook Security Settings effect the logon as well as organisational form, address books, free-busy, etc, etc. Why I hear some of your cry, well we have been having an intermittent problem for some time in that occasionally (about 2 times a week) we will get a whole bunch of calls from users that complain that Outlook is hanging while logging in. The numbers are small say a maximum of 40 out of 4,500, they are located on different subnets, different Exchange servers (same site), etc, etc. I want to make a plan to start working through the logon process to see where things are failing and therefore need a detailed document on how Outlook logs onto the Exchange server.
