AppLocker does NOT require a Windows Server 2008 R2 DC

Documentation from Microsoft regarding the new feature AppLocker in Windows 7 (and Windows Server 2008 R2) early stated that to be able to use AppLocker you must have a “Windows Server 2008 R2 Domain Controller to host the AppLocker rules”. I have seen this information several times since then and at a seminar I payed a quick visit to yesterday regarding Windows 7 this particular questions was raised.

Of course I had to make sure what’s really going on here and I have now verified that AppLocker works perfectly fine in environments where there are only Windows Server 2003 DCs or Windows Server 2008 DCs. I can see no reason what so ever for AppLocker to require a Windows Server 2008 R2 DC to function. The only requirement is that you’re running Windows 7 Enterprise or Windows 7 Ultimate edition to be able to use th powerful feature of AppLocker.

Hotfix saves power on AMD CPU:s for Windows Vista, 7 and Server 2008 R2

Microsoft have just released a hotfix for Windows Vista, Windows 7 and Windows Server 2008 R2 that potentially can reduce CPU power consumption by ten percent for AMD processors, specifically ones supporting the power state C1E. This includes popular CPUs such as AMD Phenom and Athlon range of CPUs.

The hotfix can only be obtained by contacting PSS (Product Support Services) or by requesting it for instant download via the KB article below.

KB974090: An update is available that allows for a potential power saving in an AMD multicore processor that is running an x64-based version of Windows Vista SP2, of Windows Server 2008 SP2, of Windows 7, or of Windows Server 2008 R2

Active Directory Administrative Center makes you do things in fewer steps

A new tool in Windows Server 2008 R2 that you must not miss is the Active Directory Administrative Center. The tool is far from the speediest to load but once you’ve got it started I promise you that you will find it very convenient to use for account and other Active Directory object management. As with the user interface, new search tools and more in Windows 7 the Active Direcory Administrative Center in Windows Server 2008 R2 makes you do things in fewer steps and eases your daily work!

Be aware of a problem when renaming domain controllers

If you have renamed a Windows Server 2008 or Windows Server 2008 R2 domain controller you should be aware of  a problem. The problem is that a DFSR object is not renamed to the new name. This does not cause any problems until you remove the domain controller in question and after doing a demote or cleaning it up with metadata cleanup the object will become orphaned. So if you have renamed 2008 or 2008 R2 DCs you should follow the steps in KB2001271 to fix this.
