1) When the target host is not reachable [ UNC validation path validation [ admin$] ]

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

3) When there is a network connection issue between the BDRSuite Backup server and the target host

For Cause 1: When added target host is not reachable - UNC Validation

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 BDRSuite Backup Server or BDRSuite Client is installed

1. Go to 'run' and type the following \IP\admin$
   
2. In place of IP, provide the 'Hostname\IP' of the target machine
   

Example: \192.168.100.100\admin$

Make sure the target host is reachable and it must be added into your Network Address Translation(NAT) gateway.

Note: Make sure the target “HostName\IP” you are trying to use is added into your network address translation(NAT) gateway. If it is reachable and you still face the above error, then proceed with the following verification:

Case 1:

Make sure your firewall does not block remote connections. Add the below rule into your Inbound firewall rules in your target machine to ensure the same

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 the following services are running in your target machine

1. Server Service Windows
   
2. Remote Management (WS -management)
   
3. Cluster Service
   

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. Add the below rule into your Inbound firewall rules in your target machine to ensure the same

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 the following services are running in your target machine

1. Window Management Instrumentation
   
2. Cluster Service

Confirmation test:

When the 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: If the target machine you are trying to push to is a local machine, do not provide any username and password, just proceed to connect

Step 4: If you face any issues, recheck the solution and wait until the wbem test becomes successful.

Once successful, proceed to add the desired Host.

For Cause 3: When there is a network connection issue between the BDRSuite Backup server and the target host

Steps:

1] If we get the following error message "Unable to connect to the Target host. Check the Network ...........", we need to add the BDS agent Machine / HostName in the below mentioned path of BDRSuite Backup server. {Automatic push}

Windows BDR Server:

C:\Windows\System32\drivers\etc\hosts

2] For Windows OS or Linux OS machine(Problematic agent machine), we can add the IP address and HostName at the bottom of the file. {In BDRSuite Backup Server}

[Eg:- 192.168.xxx.xxx WIN-9URRRSBMXX ]
