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.

    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
