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).

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 AppAssure 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 AppAssure Core and any clients that it backs up:
1.
On the 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.

Verifying name resolution (if applicable)

If the machine you are trying to back up uses DNS, verify that DNS forward and reverse lookups are
correct.
The port number on which the AppAssure Core communicates with the agent
on the machine.
The user name used to connect to this machine; for example, administrator.
The password used to connect to this machine.
