When you try to activate Key Management Service (KMS) from a client computer through Volume Activation Management Tool (VAMT) or Microsoft Office 2010 or Office 2013 Activation Wizard, you receive the following error message:

0xC004F038: The Software Licensing Service reported that the computer could not be activated. The count reported by your Key Management Service (KMS) is insufficient. Please contact the system administrator.

0xc004f038-error-1251999

To properly analyze and troubleshoot activation and validation issues, you require a complete copy of the report created with the MGADiag tool.

As part of Microsoft's Volume Licensing program, the minimum number of licenses in a package is 25, each Volume Licensing customer receives a special CSVLK key (or KMS host key) to activate an internal KMS server. Internal clients (Windows and MS Office) can be activated on this server via the KMS server without having to contact Microsoft activation servers over the Internet.

Wrong version key

Each Windows product key is associated with a version of Windows. For this case, when you enter a product key for Windows Enterprise edition to activate Windows 10 Home or Windows 10 Pro. As Enterprise ISO is separate from Windows 10 Home and Pro versions, make sure you download the correct ISO from Microsoft Server .

You are not connected to your workstation network.

Computers that are activated through volume licensing in a company must pass through the network of workstations. Even though the test is not done daily, but when it happens, you must be connected to your work network. Regardless, if you are connected to your work network and this error persists, you may need to change your network settings. Contact your organization's support representative for more information.

If it's not possible to connect to your support team, but you have the key, you can activate Windows yourself. Go to Settings > Update & security > Activation, then Change Product Key, then enter your 25-digit product key. You may be prompted for an administrator password or confirm your choice.

Here are some troubleshooting methods:

  • Check that the DNS is configured correctly.
  • the office in 2013, the office in 2016 and the windows in 2016 km from the KMS Schlüssel data center
  • installed on the KMS server.
  • You can activate Office and Windows Server 2016 clients with the new KMS on Windows Server 2016.
  • The old Windows 2008 R2 KMS servers are still active.
  • If I manually point the Windows 10 client to the old KMS server on Windows 2008 R2, I can activate Winodws (slmgr.vbs/skms).
