...The script does the following:
Waits (a definable length of time) for the network services to be available
(DHCP, DNS & AD)
Sets the LocalHostName, HostName and ComputerName if neccessary
Sets the login screen message to reflect
HostName
Workstation AD OU path
Network issues (if any)
Sets Remote Desktop computer info fields to show boot timings and AD OU.
The boot timings show how long it took to load DHCP, DNS, AD etc, and the total time it took to boot up.
