Hi Sudhakar,
Are the keyboard, mouse and screen connected directly to the ESXi host, or are you using a KVM-switch or KVM-over-IP system? Your description makes it sound like there is a KVM switch of some sort in the way and it doesn't like the ESXi host for some reason. Maybe the "VM232" is a named port on a KVM, or the name or model of the KVM...
Cheers,
