Active Directory tasks failing for 2008/2008R2 Servers in SCOM 2007 R2

  • Article

Recently, I deployed Active Directory Management pack (version 6.0.7065.0) in my SCOM 2007 R2 environment. To check health of one of my domain controller (2008R2), I tried to run DCDIAG task from SCOM console and I got the error below. I tried launching other AD related tasks from my SCOM Console like repadmin, netdom and got similar error. I thought of updating my AD MP to latest one (6.0.7670.0) but got the same problem.

I went through the error message and did some troubleshooting.Finally I was able to fix this. So in this blog we will discuss cause of this problem and some ways to fix this.

Cause: These AD tasks in SCOM were trying to execute from directory C:\Program files\Support Tools. This path was correct in 2000/2003 Servers but in 2008/2008 R2 servers these tools are part of Core OS. Since SCOM tasks are still trying old path, they failed to locate those tools.

Some possible ways of troubleshooting: I tried three different ways that proved helpful to me to fix this issue.

1) Override the path while running the tasks: This way every time you run any task, you can change the path of execution. It will not save the new path. Click on Override

Change the path from %ProgramFiles%\Support Tools to %windir%\system32.

Click on Override and run the task.

Concern with this is that it will not save the Overridden path and so you need to change it every time.

2) Use MKLINK: We will create directory symbolic link using MKLINK. You can find more about MKLINK here . You can run below given command on 2008/2008 R2 domain controllers one by one manually. Once symbolic link is created, you can launch the task from SCOM console.

3) Using PSEXEC: If you have big enterprise and good number of domain controllers, you can use PSEXEC to create symbolic link for you. Download PSEXEC from here. I created a text file on my SCOM server with name of each domain controller in separate line. Below is the syntax used:

Once the command got completed, I was able to run DCDIAG, REPADMIN and other AD related tasks from my SCOM Console.
