Error Adding Office KMS Keys “0x80072F8F”

KB ID 0000584 


Seen when adding an Office 2010 KMS key on a Windows 2008 R2 KMS Server.

Note: Using the Microsoft Office 2010 KMS Host License pack as per this article.


An error occurred: 0x80072F8F
To display the error text run the following:
slui.exe 0x2a 0x80072F8F


1. If you do run the command that they have asked you to, all you get is;

A Security error occurred

2. Not very helpful, however some Google searching turned up the solution. Check the time on the KMS server is correct, mine was way out.

Note: This had happened because the domain controller was on an ESXi host with the incorrect time, the KMS server took its time from the domain controller when it booted. (Domain clients typically take their time from the DC holding the PDC emulator role).

Locate your FSMO Role Servers

3. With the time fixed, try once again, and you should be successful.
