2. Upgrade your Windows OS
Oftentimes, functional problems arise with the KMS server when your Windows OS isn’t correctly licensed.
Having an original license not only ensures that your product is legit, fully functional, and reliable, but you also get regular updates that prevent bugs.

Before activating yourOfficecopy, we need to make sure that on the client computer, Windows is activated.
4. Check if you have more than 25 clients
5. Check the client communicated with the host
On theKMShost computer, look in the Application event log for event ID 12290. Check this log for requests made by the client’s computer.
If there are no requests, it means that the client could not communicate with the host.
6. Open the right port
Make sure that there are nofirewallrules that block TCP traffic on theKMSport. The default port value is 1688. If you don’t know the port you can find that out on your host computer.
7. Configure DNS properly for multiple KMS hosts
When using KMS, the host computer must be discoverable in your local network. The first host computer automatically publishes its existence when it creates a SRV record on the DNS server.
The rest of the hosts cannot change or update SRC if the DNS server is not configured properly.
8. Newly added computers don’t increase the KMS count
Sometimes client computers look identical to the host and therefore it doesn’t count them as separate.
Finally, if you are still having issues, you can switch to anAD-based activationby following the official documentation.
Can you have 2 KMS servers?
It is not recommended to have more than one KMS server for Windows and Office as it puts additional work into implementing and managing it properly.
