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.
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.
<BackupExec Install Path>\SDR\win32\Configuration\HKLM.System.reg
<BackupExec Install Path>\SDR\win64-x64\Configuration\HKLM.System.reg
