The following error appears when a backup job is run. Backup failed: Backup: Vizioncore.vRanger.Domain.Common.PhysicalTargetDevice failed.
The backup process is unable to write to the repository location. vRanger has detected that your local LAN Manager authentication level is set to 'Send NTLMv2 response only\refuse LM & NTLM'. Please change your authentication level to 'Send LM & NTLM responses' and retry the job. Or configure your ESX host to initiate NTLMv2 authentication. This is done by adding/modifying this file on your ESX host:
Append these lines to the file:
client ntlmv2 auth = yes
Your ESX host will not need to be restarted.
The issue occurs when Network Security under the Local Security policy or a global security policy is set to Send NTLMv2 response only\refuse LM & NTLM.
The following these steps will resolve this error.
Putty into the ESX host. (Will have to be done on every ESX host)
Client ntlmv2 auth = yes”
