Hi

We are using Windows 2003 AD.

We have many different applications, and some need to authenticate to AD using either Kerberos or NTLM.

Could someone please clear a few things up for me -

i. Which one is the 'preferred' authentication mechanism - Kerboros or NTLM?

ii. MS products such as Outlook, SharePoint etc - which one do they use?

iii. If I used a product like Wireshark for example, is it possible to see which authentication mechanism was being used?

iv. Are there any benefits to using Kerberos over NTLM (or vice-versa)

v. Which one is the 'newer' protocol?

vi. Can their ports be changed?
