About KMS Activation in Depth

Bhim Charan Murmu 21

I just want to know how to make easy for KMS server Host machine to easily communicate with KMS Client machine (In this case this is my PC) for Windows 10 OS (In case) and MS Office product activation by Key Management Services by tweaking some settings in DNS and Windows Firewall cuz I am using internet through an organization network (ex. University).

I am asking this because I tried to activate MS Office Professional Plus 2019 - Volume Licensed by KMS through Command Prompt but kept getting this message "No Key Management Services server could be contacted".

Also I checked tcping (by CMD) of KMS server which results in failed communication.

I am currently on Windows 10 v20H2 Build 19042.1083.

Any detailed support in this matter would be greatly appreciated.

Hello,
Are you going through a VPN to access the KMS host?
How are you connected to the organization network?

First, No I am not using VPN to access the KMS host server.
Second, I am connecting to my organization network through login page provided by organization.

Hello,
What happens when you click the login page from your organization? Does it work like a remote desktop session?
KMS works through VPN,
When you run this command from an elevated CMD prompt what happens?
I see below you mention it doesn't work
nslookup _vlmcs._tcp -type=srv

this command is trying to reach your organizations DNS server to get the address of the KMS host.

Please check these articles (confirm your KMShost is correctly registered in your DNS)

https://learn.microsoft.com/en-us/deployoffice/vlactivation/configure-dns-to-activate-office-by-using-kms
Configuring DNS

Also, at the KMSclient computer, check that the KMSclient computer can discover your KMShost correctly:

nslookup _vlmcs._tcp -type=srv

Source case:

2) https://learn.microsoft.com/en-us/previous-versions/tn-archive/ff793405(v=technet.10)

First link assumes that I am using Microsoft's Volume Licensing Service Center (VLSC) but in my case I am not using it for KMS activation instead I am using my own created KMS server with different KMS hostname address.
Second link returns 404 error on opening and it may have been deleted from the documentation

sorry, I revise the second link address.

First link assumes that I am using Microsoft's Volume Licensing Service Center (VLSC) but in my case I am not using it for KMS activation

you mean that you don't use the volume license from VLSC? where you bought the KMS host key? How you created KMS server with different KMS hostname address? If you want to activate Microsoft Office product, you need to but its license from Microsoft official channel.
