Authentication prompt when opening or creating office document with Windows7 and Moss2007
Hi, In December 2009 I had problems with the web client service under Windows 7 and fba authentication to our moss 2007 server when opening or creating a new document. I escalated the problem to Microsoft and it was indeed a bug with the web client service. (Release fix: April 2010) (For the moment I using a beta fix in our test environment till the release) Previous Discussion: http://social.technet.microsoft.com/Forums/en-US/sharepointgeneral/thread/b9278a85-d14c-455a-bac9-ef5a80819d41 Because we have here at the university all the pc’s in a separate domain and the servers in another domain without trust, we using always FBA authentication through ISA2006. This month we start to move only the Windows 7 clients to the ‘server’ domain. In theory we shouldn’t have any problems with authentication popups in the same domain. In practice we have always an authentication popup when opening or creating a new office document. Detail: We using moss2007 (sp2 CU update October 2009) on windows 2003 64 bit servers with Kerberos enabled on the web applications. Ntlmv1 is blocked on the servers. I’ve tested the different security zones in IE8 with protected mode enabled and disabled. After tracing the https traffic, the ‘401 unauthorized’ error’s started after using the Microsoft-Webdav-MiniRedir/6.1.7.600 user agent. I think that there is still a problem with the web client. Is there someone that experience the same problem? And do you know what my problem can be? Regards,

I forgot to tell you that we using FQDN.The site is under the 'local intranet' zone in IE8. When I use the option ' Automatic logon with current user name and password' then the pop-up doesn’t show up anymore. Is it normal that you need to change the IE custom settings when using FQDN? Regards,

Hi, I was searching in the wrong direction. This was the problem: “If the URL contains periods, the server is assumed to be on the Internet. The periods indicate that you use an FQDN address. Therefore, no credentials are automatically sent to this server” This article solved my problem. (Works also for Windows7): http://support.microsoft.com/kb/943280 Regards,
