## Problem

During imaging/deployment, the target machine is unable to communicate with the Central Server.

## Cause

1. The target machine does not have a valid IP Address.
2. The network on which the target machine is connected might have blocked the Central Server.

## Resolution

To resolve this problem, follow the step-by-step process given below:

### Step 1. Ensure that a valid IP is assigned to the target machine

- Go to command prompt.
- Execute the following command: **`ipconfig /all`**
- Under Ethernet adapter, check if a valid IP address (IPv4 Address) is assigned. A valid IP will have the preferred tag with it.
