We can analyze the events on each server or collect them to the central Windows Event Log Collector. The apps that cannot use Kerberos can be added to the exceptions. This will allow them to use NTLM authentication, even if it is disabled at the domain level.
Members of this security group can authenticate only using Kerberos. Never again lose customers to poor server speed! Let us help you. Your email address will not be published. Submit Comment.

Deploy the auditing in a test environment as long as all applications have been inventoried and there is no reasonable possibility of users running unknown applications in production.
Deploy auditing in the production environment if not all applications can be inventoried. Deploy the incoming and outgoing auditing policies to all servers and computers. Deploy the domain auditing on DC's only; it will have no effect on member computers. Come up with an audit event collection strategy. This may include third parties, Event Subscriptions , or other methods.
The key is to make sure that the events are not lost. Make sure the NTLM audit event logs are increased to a large enough size that they do not constantly wrap. Thus, you can verify if Kerberos user authentication works correctly in different apps. It shows you that there is an application still using NTLMv1. Disabling NTLM immediately can have broken an application.
Make sure this is tested properly. I would like to suggest some different code to run against your domain to get the events around NTLM: must be run from a DC for the domain controllers you want to collect with the same credentials example enpro domain iad0dc Of course I left in some comments which should have probably not been included.

Applies To: Windows 7, Windows 8. This security policy reference topic for the IT professional describes the best practices, location, values, management aspects, and security considerations for this policy setting.
This policy setting does not affect interactive logon to this domain controller. The domain controller will allow all NTLM pass-through authentication requests within the domain. The domain controller will deny all NTLM authentication logon attempts using accounts from this domain to all servers in the domain. NTLM can be used if the users are connecting to other domains.
