vSphere Disable Timeout

KB ID 0001118  Problem One annoying thing about the vSphere web client is the fact it throws you out after a period of inactivity.

vSphere: Get ESX Server Serial Numbers

KB ID 0001670 Problem A few weeks ago I needed to sort out some extended warranty for a customers servers. To do that  I needed the serial numbers of those servers, (a mixture of IBM/Lenovo and Dell Servers). As I didn’t fancy a drive to two different datacenters, I wanted to try and get them programatically.
