Windows Vista RC2 was released this past weekend. For those with B2 or RC1, you can update over the top of your existing installation with the same product key. The new build is 5744.
Yesterday I received an email from the OneCare Beta team. Windows Live OneCare v1.5 Beta is now available and it works with any Vista build RC1 or newer. It seems to be working fine with my RC2 installation on my laptop.
I've been doing some .NET DirectoryServices development and need to verify somethings using a simple LDAP lookup. Vista doesn't come with the standard Support/Tools that Windows XP and Windows Server 2003 did. So I couldn't find a copy of LDP.exe. Moreover, you can't install the support tools that come with XP. It turns out that you need to install from the Windows Server 2003 disc/image. You get a warning, but it runs fine in Windows Vista.
