I wonder what is default authentication protocol in window 2008 r2 (Active directory). Is using kerbose or NTLM ? Pls advice. Thx !!

Kerberos is the default authentication protocol in Windows 2000 and later Microsoft OSs. Windows uses a negotiation mechanism to determine which authentication protocol will be used. If the Kerberos default fails or isn't supported by one of the client or server components involved in an authentication, Windows will fall back to NTLM.http://www.arabitpro.com
