All of a sudden, my 2008 R2 file server has lsot activation. every time i try and reactivate it using slrgr.vbs it comes up with the error:
"on a computer running Microsoft windows non core edition, run 'slui.exe' 0x2a 0x80070426 to display the error text' error:0x80070426
Im also unable to start the software protection service and it comes up with the error: error 5: access denied!
Have you had a look at this thread?
KMS activation failing
I have but it doesn't help. even if i type slmgr.vbs /dlv it come up the "on a computer running Microsoft windows non core edition, run 'slui.exe' error.
I Managed to sort this using the following link, and a restart of the server. Strange now though as i have a couple on win 7 clients gone the same way!!!
