Discovery Phase "NTSTATUS: NT_STATUS_ACCESS_DENIED"
Will you please confirm if the mentioned servers are joined to a domain or workgroup servers?
The NTSTATUS: NT_STATUS_ACCESS_DENIED - Access denied indicates the account does not have the correct privileges to access the WMI classes on the remote host. Please find the below link to a Microsoft article that will detail the required permissions for enabling an account for remote WMI access:
UAC & WMI (Account Requirements)
As an option, you can use Wbemtest.exe utility that is included on all Windows systems to confirm the user account has the correct WMI privileges. Please find the below detail on using wbemtest.exe.
Below are instructions on using wbemtest.exe to verify the account has the correct privilege level and that the service is running:
1) In Windows, select start, type wbemtest, select enter.
2) Select 'Connect' in the top right corner
Namespace = [file://(computer]\\(computer name)\root\cimv2 - enter this replacing computer name with hostname (or IP address) you wish to test to.
Enter the Windows account username and password
Successful authentication will result in seeing WbemServices and the tabs are no longer greyed out. Failure to authenticate will result in an error message.
Once you have resolved the privilege issues please select request rescan in the virtual appliance dashboard to update the inventory.
