Need help to activate my windows 10 ltsc_2021

Question

I installed a windows 10 using this iso: en-us_windows_10_enterprise_ltsc_2021_x64_dvd_d289cf96.iso

2. Activation Commands (run cmd as Administrator)

slmgr.vbs /skms <our internal server>

slmgr.vbs /skms-domain <our domain>

slmgr.vbs /ato

But the activation failed, I got this error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service(KMS) could be contacted.  Please see the Application Event Log for additional information

Someone could help with me?

Thanks!

Hello，

Here are a few things you can try:

1. Check if the KMS server is reachable from the computer you are trying to activate. You can do this by pinging the server from the command prompt.
2. Check if the KMS server is running and accepting requests. You can do this by running the following command on the KMS server: slmgr.vbs /dlv
3. Check if the KMS server has the correct product key installed. You can do this by running the following command on the KMS server: slmgr.vbs /ipk <product key>
4. Check if the KMS server has reached its activation limit. KMS servers have a limit on the number of activations they can perform. You can check the activation count by running the following command on the KMS server: slmgr.vbs /dli
