We run Windows XP, Vista and are now testing Windows 7 in our corporate environment. Thus far all of our Win7 installations have been x64 installs with the same net result that we are having to authenticate to every corporate intranet site. Single sign on works in Firefox and all versions of IE on other OSes. Neither IE or Firefox works with single sign on in Win7 leading us to believe it is something to do with Win7.
We do not have this problem in Windows XP or Vista. Is there a setting in Win7 that allows for single sign on? Is there a domain setting specific to Win7?
