How to disallow LDAP anonymous binding for Windows server 2008

view story

http://serverfault.com – I have a Windows server 2008 server under domain and security scan found out that LDAP anonymous binding is allowed. So i need to disable the anonymous binding for my domain. I have found a way to do it with Server 2003 using adsiedit.msc, but can't find the same option for server 2008. Can someone point me right direction for it? Thanks! (HowTos)
