We are in the process of upgrading AD from Windows 2003 R2 to Windows 2012 R2. Are there any good articles on this?
Also, how the forest trust to be taken care of during the upgrade? we have applications that use NTLM, what is the recommended option is the application do not support NTLM v2 ?
Are there any good utilities that I can run on AD to let me know what are the applications authenticating with AD?
