4. Click Connect.
5. 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 AppAssure Services and RPC are running.
d) Verify Domain Name Service Lookups (if applicable).

Check 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 AppAssure components to run.

Check The Firewall Settings

If the client is connected properly to the network, but cannot be seen by the AppAssure Core console, check the firewall
to ensure that necessary inbound and outbound communications are allowed.
To check the firewall settings on the AppAssure Core and any clients that it backs up:
1. On the AppAssure 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.
5. Ensure the AppAssure Core and ports display Yes in the Enabled column.
6. If the rule is not enabled, right-click on AppAssure Core and select Enable Rule.
7. Click Outbound Rules and verify the same for AppAssure Core.

Verify Name Resolution (If Applicable)

If the machine you are trying to back up uses DNS, verify that DNS forward and reverse lookups are correct.
To ensure that the reverse lookups are correct:
1. On the AppAssure appliance, go to C:\Windows\system32\drivers\etc hosts.
2. Enter the IP address of each client that backs up to DL4000.
