I have setup my farm to use kerberos but i am reading that in order to get the ssp to use kerberos I need to apply the infrastructure update. where is this update? is it a part of SP2?

I assume you are making reference to the information on Technet here: http://technet.microsoft.com/en-us/library/cc263449(office.12).aspx#section14 This has already been answered at http://social.technet.microsoft.com/Forums/en-US/sharepointadmin/thread/0efdffe9-c98c-44ac-a2bf-6f81c92d7b61 Basically you do not need to install the infrastructure update first as the changes are rolled up in SP2.Benjamin Athawes - Twitter: @benjaminathawes - Blog: http://mossblogger.blogspot.com - Email: mail at bathawes.com
