Background

Wyse thin clients use ini files to grab their settings upon startup. By default the thin clients will look in \\WDM-Server\c$\inetpub\ftproot\Wyse\wlx\ for the WYSE.ini file. This is a base file that should only contain generic settings for all thin clients, like the WDM server or the VMware View server. For individual settings, like screen resolution, a $MAC.ini file is needed. This is simply a copy of the Wyse.ini file that includes any settings that are unique to a particular thin client. The name of this file should be the MAC address of the thin client.

This post assumes you have the following:

The script

<#
Usage: WyseINI.ps1 -s <HQ or RW, wherever the thin client will connect to> -m <MAC address of the thin client> -r <screen resolution you want to set (input width setting only)>
#>
[CmdletBinding()]
