When a client computer PXE boots, it will return PXE E78: Could not locate boot server.

The problem is that the network is not forwarding the correct data across the network. You can troubleshoot this by simply following the steps below.

1. Problem of the firewall. Make sure CCBoot is allowed in the firewall (Figure 1-1)

Open Firewall Settings

2. Problem of Boot server IP address not configured properly. Make sure your ccboot server ip address and DHCP settings is set correctly.
             A. Open Command-line and Check your IP address using ipconfig command (Figure 2-1).

Open CMD

            B. Check Scan DHCP in the CCBoot DHCP Settings. Make sure no DHCP conflict and DHCP settings configured properly. Open the right port. Two available options, either you are using the CCBoot Server DHCP or third party DHCP server. Both are supported by CCBoot, We always recommend to use CCBoot DHCP server (Figure 2-2).
