Error 0xC004F06C, KMS determined that the request timestamp is invalid

Since the Volume Activation Error message says “The system time on the client computer is too different from the time on the KMS host” the problem is very straightforward. The system time on the client computer i.e. yours is too different from the time on the KMS host.

Time sync is always important. Be it on with the Internet Time Server or when you are with the Enterprise. Since your enterprise computer depends on a lot of things from the server, including security,  it has to be in sync with it.

To fix this, you need to change the system time on the client to sync with KMS. This error suggests that you are using UTP or and is independent of Time Zone selection.

Network Time Protocol (NTP) time source

  • To use NTP time source on your client machine, you can change registry settings on your computer.
  • Open Registry Editor and navigate to: HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient
  • Change the value for “Enabled” to 1. This means the NtpClient provider is enabled in the current Time Service.

If you are not able to edit registry settings, you will have to connect with the admin to resolve this.

Active Directory Domain Services Time Source

To find out if your client is using ADDS time source, you need to examine the REG_SZ value.

  • Open Registry Editor and navigate to at HKLM\System\CurrentControlSet\Services\W32Time\Parameters\Type.
  • Check the value REG_SZ. If it is set to “Nt5DS” then the computer is synchronizing time with the Active Directory time hierarchy.

If it’s not the same, you need to connect with Admin to get it configured correctly.

Once the client is in sync with the KMS server, your activation error 0xC004F06C should be resolved.
