Info [SureBackup] [VMNAME] [ScriptTests] Begin 'Predefined script 1: name DNS Server, starting...' Error Failed to create process with net logon (ERROR_ENVVAR_NOT_FOUND) (System.Exception) This is the DNS Script test specifically. The various script tests will have different names, however the error will remain constant.
Microsoft KB3139914 has been installed; it pertains to the secondary logon service.
There are three possible solutions:
Uninstall the update if possible.
Leave credentials blank as a workaround. This entails a recreation of the Application Group or Linked Jobs as at present there is no way to remove credentials from the VM options in either of these, once they have been set.
Support has a hotfix that can be implemented to address this issue without removing credentials or the update. Note that this update can only be applied if you are running Veeam v9 update 1 (188.8.131.521)
