Cause:

The Error “Problem while fetching VM information using WMI repositories” occurs due to below-mentioned reasons:

1) When added target host is not reachable

2) When there is an issue in accessing Windows Management Instrumentation [ WMI ] of your target host

3) When the provided target host credentials have been changed but yet to be updated in Vembu BDR/Vembu VMBackup client

4) If added target host is of Hyper-V then make sure Hypervisor is available in your target machine

5) When BDR (or) VMBackup client service logon account is in “local system account“ instead of the administrator user

Solution:

For Cause 1: When added target host is not reachable

Target host Remote share [ Admin$ ] is required for copying the VIS installer to the target machine.

You can confirm UNC validation by verifying the admin$ share access manually from your Machine where “Vembu BDR” or “Vembu VMBackup" had been installed.

Test for admin$ access

    Go to 'run' and type the following  \\IP\admin$ 
    In place of IP provide the “Hostname\IP “ of the target machine 
    Example : \\192.168.100.100\admin$

If you don’t see any network connectivity issue on proceeding further, it confirms UNC validation is a success.

If you face any network connectivity issue, then below are the steps to troubleshoot:

Case 1: Make sure your firewall does not block following remote connections ,if so please add the below rule into your Inbound firewall rules in your target machine

   Step 1: Open control panel 
   Step 2: Navigate to System and Security >Windows Firewall >Advanced Setting
   Step 3: In Windows firewall with advanced security, click Inbound rules
   Step 4: Inbound rules > click new rule and proceed to opt for Predefined option
   Step 5: In predefined drop-down > select “Remote Service Management “ rule and proceed with the default option to enable it and click finish

Case 2: Make sure Following services are running in your target machine

    Server Service
    Windows Remote Management (WS -management)

For Cause 2: When there is an issue in accessing Windows Management Instrumentation [ WMI ] of your target host

Case 1: Make sure your firewall does not block any Windows Management Instrumentation function, if so please add the below rule into your Inbound firewall rules in your target machine

    Step 1: Open control panel 
    Step 2: Navigate to System and Security >Windows Firewall >Advanced Setting
    Step 3: In Windows firewall with advanced security, click Inbound rules.
    Step 4: Inbound rules > click new rule and proceed to opt for Predefined option
    Step 5: In predefined drop-down > select “Windows Management Instrumentation “ rule and proceed with the default option to enable it and click finish.

Case 2: Make sure Following services are running in your target machine

    Window Management Instrumentation

For Cause 3: When the provided target host credentials have been changed but yet to be updated in Vembu BDR/Vembu VMBackup client

Update the new credentials of the target in your Vembu BDR\VMBackup client

Steps to update new credentials:

    Step 1: Open Vembu BDR\VMBackup console 
    Step 2: Navigate to Backup > Manage Servers 
    Step 3: In Manage Server, select the respective target host and click on the EDIT option 
    Step 4: You can add new credentials here with a new description and proceed to save  
    Step 5: You can also edit the existing host password directly by navigating to Management > Credential manager and proceed to edit.

For Cause 5: When BDR (or) VMBackup client service logon account is in “local system account“ instead of administrator user

Solution: Make sure Vembu BDR/Vembu VMBackup client services are running with either one of the following privileges

  • Administrator
  • User having administrator privilege

Steps to add/verify Service logon on your Server / Client machine:

    Step 1: Go to 'Run' and type “Services.msc”
    Step 2:  On Services.msc check for  “VembuBDR” or “VembuVMBackup” service accordingly from where VIS push is about to take place.
    Step 3: Right click the service [ VembuBDR/VembuVMBackup” ] and click properties   and navigate to “Logon”
    Step 4: Here provide your user details in “This Account”  column

    Example: If your user is “Administrator” and password in “Test123$”, then provide

    This account = .\Administrator 
    Password = Test123$
    Confirm Password = Test123$

    Step 5: Once user account details are updated, proceed it with by giving “Apply” and then  “OK”
    Step 6: Restart the respective service for the changes to apply

Note: In case you face any issue during service restart, then please recheck the user credentials provided during logon update.

Confirmation test:

When Above mentioned solutions are verified, perform a pre-test using WBEM utility.

    Step 1: Open “wbemtest” in your server / client machine 
    Step 2: In the namespace text box provide Target hostname\IP: \\IP\root\cimv2

    Example: \\192.168.100.100\root\cimv2

    Step 3:  Provide the username and password and click on connect 
    Note: Target machine you are trying to push is a local machine then do not provide any username and password, just proceed to connect 

    Step 4: In case of error, then recheck the solution again and wait until the wbem test becomes successful

Once successful, please proceed to add the desired Host.
