Cause:

This problem arises when VembuBDR\VembuVMBackup cannot access the target machine’s admin$ access.

It is universal share path usually required to copy the VembuInstallationService installer on to your target machine.

Solution:

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

Open 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 proceeded further, if you don’t see any network connectivity issue then you can confirm UNC validation is a success.

If you face any network connectivity issue, 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)

Once Case1 and Case 2 are verified, try UNC access again as mentioned above from your Server/Client machine in order to confirm successful UNC validation.

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.
