The first time protection is added for a machine, a base image (that is, a snapshot of all the data in
the protected volumes) will transfer to the repository on the Rapid Recovery Core following the
schedule you defined, unless you specified to initially pause protection.
15. If you receive an error message, the appliance cannot connect to the machine to back it up. To
resolve the issue:
a. Check Network Connectivity.
b. Check the Firewall Settings.
c. Verify Rapid Recovery Services and RPC are running.
d. Verify Domain Name Service Lookups (if applicable).

Checking network connectivity

To check network connectivity:
1. On the client system to which you are trying to connect, open a command line interface.
2. Run the command ipconfig and note the IP address of the client.
3. Open a command line interface on the appliance.
4. Run the command ping <IP address of client>.
5. Depending on the result, do one of the following:
• If the client does not reply to the ping, verify the server's connectivity and network settings.
• If the client replies, check that the firewall settings allow the DL1000 components to run.

Checking the firewall settings

If the client is connected properly to the network, but cannot be seen by the Core console, check the
firewall to ensure that necessary inbound and outbound communications are allowed.
To check the firewall settings on the Core and any clients that it backs up:
1. On the DL1000 appliance, click Start → Control Panel.
2. In the Control Panel, click System and Security, under Windows Firewall click Check firewall status.
3. Click Advanced Settings.
4. In the Windows Firewall with Advanced Security screen, click Inbound Rules.

Record the passphrase in a secure location. Dell Support cannot recover a
passphrase. Once you create an encryption key and apply it to one or more
protected machines, you cannot recover data if you lose the passphrase.
Re-enter the passphrase you just entered.
