hi -
We upgraded our SharePoint 2007 servers from Windows 2003 to Windows 2008 R2. It now keeps challenging users to log in several times. I have changed the authentication provider from Kerberos to NTLM, no luck.
It seems that if I uncheck the 'Enable Integrated Windows Authentication' setting in Internet Explorer 8, it helps. Is there any other way around this? Do I need to disable kernel-mode authentication in IIS 7, even though
we are still on Sharepoint 2007?
thanks
