If you have installed the latest Active Directory management pack and if you try to start an Active Directory related task e.g. DCDIAG, REPADMIN etc. on a Windows 2008 / 2008 R2 domain controller you will receive an error that these files are not found. On Windows 2003 domain controller you had to install the Support Tools as a separate download from Microsoft. These tools installed under c:\Program Files\Support Tools. Nowadays these tools are being installed under c:\windows\system32 as part of the Active Directory Tools on 2008 / 2008 R2 domain controller.
Since you can’t fix the path in the management pack directly there’s is just one possible way to get rid of this problem.
There are many posts out there but the one I think is the best way to fix this problem is to set a symbolic link on each domain controller. This means, you must execute this command on each 2008 / 2008 R2 domain controller.
mklink /D “c:\Program Files\Support Tools\” c:\windows\system32
This way you link the c:\Program Files\Support Tools\ into the c:\windows\system32 directory. It works great I have been using it all the time…
