I found this article showing that at least older versions of Backup Exec system recovery disk uses NTLM v2 but in my expereince testing SDR in Backup Exec 2012 I could only get the SDR session to log in if I reset my domain controller to use NTLM v1 authentication. Is there something that I haven't configured correctly or is this just the way it is? The security requirements of my system require me to use NTLM v2 only.

...this looks to be quite a technical question so I have hit the support flag.
Thanks!

By default SDR uses the following settings
LmCompatibilityLevel value of 1: Use NTLMv2 session security, if negotiated. Clients use LM and NTLM authentication, and use NTLMv2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLMv2 authentication.
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
If you want to change this authentication level, you have two options.
