Microsoft defender for identity lab: Domain dominance playbook

Copper Contributor

Hi,

 

I have built a laboratory with a domain controller and two destkop computer as the laboratory says:

 

https://learn.microsoft.com/en-us/defender-for-identity/playbook-setup-lab

 

In the last step, when you have injected the kerberos ticket on command prompt session and you try to run a dir on domain controller, I get always the same error message:

 

"The system cannot contact a domain controller to service the authentication request. Please try again later."

 

Has anyone gotten it to work?

 

Thanks a lot.

Hi eliasml,

Did you check and verify all MDI prerequisites? These also apply to the lab itself: https://learn.microsoft.com/en-us/defender-for-identity/prerequisites

Kind regards,

Yes, I did it. A few times.
