Microsoft Hyper-V • Re: Upcoming V13 NTLM Deprecation

Hi ENBS,

For Windows VBR, NTLM will remain available after upgrade. Just as today with V12, the choice between Kerberos and NTLM when both are available will be based on the OS settings, that is Veeam will use whatever protocol the OS is configured to use. Of course by default Kerberos has preference and overall we highly recommend that you start deprecating NTLM usage.

The software appliance on the other hand operates in FIPS certified mode and has DISA STIG hardening applied, which makes it impossible for us to use NTLM in principle.

P.S. Hyper-V communication without domain is not a problem for software appliance, you just need to use Veeam Deployment Kit.
