Auto Deploy error, the physical server(on which ESXi is planned to be installed) shows "PXE-E18：Server response timeout."

Products

• VMware vCenter Server

Issue/Introduction

The Physical Server cannot establish a connection to the TFTP and DHCP server.

Environment

VMware vSphere 8

Cause

The problem lies with the server hosting the DHCP and TFTP services. There is a connectivity issue between the physical server and the TFTP/DHCP server.
The Auto Deploy process has not reached vCenter, so the issue has not yet involved vCenter.

Resolution

This problem is not related to vSphere; the user should collaborate with their network team to resolve the connectivity issue.

Additional Information

Note: If DHCP server resides in VMware NSX environment, please refer to KB 320299 to unblock DHCP Server Block.
