Dell WMS – DNS Configuration

Release date: February 21st 2021, Updated February 3rd 2023

Welcome to my Dell Wyse Management Studio section. In this sub-section I will describe how configured the necessary DNS records. I will be creating the following four records:

• _WMS_MGMT – This record points to the Wyse Management Suite server URL
• _WMS_MQTT – This record directs the device to the Wyse Management Suite Push Notification server (PNS). MQTT is a component of WMS which is required to notify the thin clients
• _WMS_GROUPTOKEN – This record is required to register the ThinOS devices with Wyse Management Suite
• _WMS_CAVALIDATION – This record is required to toggle CA Validation between the devices and the WMS server

These records are described in detail in the documentation here: Dell Wyse Management Suite Version 4 Administrator’s Guide

DNS Records:

Record Type	Service	Protocol	Value
Service Location (SRV)	_WMS_MGMT	_tcp	wyse-01.ad.admin.frelab.net
Service Location (SRV)	_WMS_MQTT	_tcp	wyse-01.ad.admin.frelab.net
Text (TXT)	_WMS_GROUPTOKEN		defa-8A2Ui@k<
Text (TXT)	_WMS_CAVALIDATION		False

I launch the DNS Administrator Snap-in, right-click the “_tcp” zone and select Other New Records…

I select Service Location (SRV), Create Record…

I name this record “_WMS_MGMT” and enter the FQDN of my WMS Server, OK…

Similarly, I create a Service Location (SRV) record for the “_WMS_MQTT” record pointing it to the FQDN of the WMS Server, Done…

Prior to creating the TXT record “_WMS_GROUPTOKEN“, I copy the defa-string the WMS GUI. I will be using the group token from the Unmanaged Group.

Next, I right-click my DNS zone and select Other New Records…

I select the Text (TXT) record type, Create Record…

I enter the record name “_WMS_GROUPTOKEN” and paste in the defa-string I copied in the steps above, OK…

Finally, I repeat the TXT-creation procedure above to create the “_WMS_CAVALIDATION” record, I click Done once finished.

I enter the Record name “_WMS_CAVALIDATION” and “False” as text, Once finished I click Done…

This concludes the configuration of the necessary DNS records. The next logical step for me is to configure my Groups in WMS Server, this I have documented here: Dell WMS – Device Groups
