server manager encountered an unexpected error while collecting data about the stutus of this computer
HRESULT:0x80070543

Problem:
The server-wide COM security settings have been changed to have a “Default Authentication Level” of ‘None.’

Solution:

1. Using elevated permissions, run Dcomcnfg.exe

2. In the “Component Services” window, navigate to ComponentServices->Computers->My Computer.

3. Right-click on “My Computer” and select [Properties] from the context menu.

4. In the “My Computer Properties” dialog, select the [Default Properties] tab.

5. Change the “Default Authentication Level” drop to ‘Connect’; if it is set to None.

7. Change the “Default Impersonation Level” to Identify; if it is set to something else.

8. Press the OK button in the “My Computer Properties” dialog.

Doing the following activates it using the MAK key:

1) Open a cmd shell as Administrator.
2) Type the following (but use your key instead of all the X’s)

slmgr -ipk serial
3) The prompt will return right away, but there is a licensing task that it started (if you look in Task Manager you can find a task SLsvc using up cpu, I assume this is where the licensing is going on).
4) After a while a dialog will pop up saying that it has been activated.
