Recently we installed the KB (KB958830) which adds the Remote Server Administration Tools (RSAT) to a Windows 7 computer. Installing this KB is a two step process: first you install the bits, afterwards you enable the required tools in the Turn Windows features on or off section of the Windows Configuration Panel.
In our case adding tools like Active Directory Users & Computers (ADUC) went fine, but we were unable to add the Active Directory Administrative Center:
Clicking OK starts the configuration of the selected components:
Which finally result in:
In words: An error has occurred. Not all of the features were successfully changed.This is followed by a prompt to restart the computer. In my case I ignored this. After some googling I started suspected are favorite trouble-causer: Antivirus. So I started the McAfee console as an Administrator, unlocked the interface and disabled the On Access Scanner. Remark: in order to do so you first need to stop the Access Protection.
And now I could check the Active Directory Administrative Center and the configuration finishes gracefully… Probably some exclusion would fix this for good, however for now I lack time to dig deeper…
Also related, in the Event Log, below the Setup section, I found the following event entry:
Update RemoteServerAdministrationTools-Roles-AD-DS-AdministrativeCenter of package KB958830 failed to be turned on. Status: 0x80070643.
Perhaps this might help people finding this post faster.
