0xC004F074 Error: Windows Activation Server Connection Issue

1. Check KMS Server Availability

Ensure that your system can access the KMS server. If you’re part of an organization, contact your IT administrator to verify that the KMS server is up and running.

1. Open Command Prompt as an Administrator.
2. Type the command:
3. nslookup <KMS_Server_Name>

• This checks whether your machine can reach the KMS server through DNS.

2. Re-enter the Product Key

If the activation key has been entered incorrectly or has expired, re-entering a valid product key can resolve the error.

1. Open Command Prompt as Administrator.

Type the following command to reset the product key:

slmgr.vbs /upk

1. Then, enter the new product key with this command:
2. slmgr.vbs /ipk <Your_New_Product_Key>
3. Afterward, try to activate Windows again.

3. Activate Windows Using Phone Activation

If you're unable to activate online, you can attempt phone activation:

1. Open Command Prompt as Administrator.
2. Run the following command to initiate the phone activation process:

slui.exe 4

1. Follow the prompts and call the Microsoft activation hotline to complete the process.

4. Restart the Windows Activation Service

If there are issues with the Windows Activation service, restarting it can sometimes resolve the problem:

1. Press Win + R, type services.msc, and press Enter.
2. Scroll down and locate Software Protection.
3. Right-click on Software Protection and select Restart.

5. Reconfigure DNS Settings

Ensure that your DNS settings are correctly configured to allow access to the KMS server:

1. Go to Control Panel → Network and Sharing Center → Change Adapter Settings.
2. Right-click on your active connection and select Properties.
3. In the Internet Protocol Version 4 (TCP/IPv4) properties, ensure that your DNS server settings are correctly configured, either manually or via automatic DNS.

6. Run Windows Activation Troubleshooter

The Windows Activation Troubleshooter can help automatically detect and fix issues related to activation:

1. Go to Settings → Update & Security → Activation.
2. Click on Troubleshoot and follow the on-screen instructions.
