Hello everyone!
The last week we are getting the following alert in our environment (SCOM
2007 SP1):

************************************************
Alert name: IIS Discovery Probe Module Failed Execution
Alert rule: IIS Discovery Probe Module Execution Failure

Error doing IIS DiscoveryError: 0x80070002

One or more workflows were affected by this.

We only get these alerts from Windows Server 2008 machines that hold the Web

On the servers where the alert originates from an Operations Manager event

NicoDavis,

Were you able to resolve this issue? We are seeing the same issue for a
Windows 2003 server.

Hi,

I had the same issue and here is the cause:

- The IIS management tools were installed (The IIS Admin Service) but no
other IIS part.

The discovery looks for \Services\IISAdmin to evaluate whether or not IIS is
installed. So IIS was "discovered". But then de further steps failed as
nothing else is installed.

On the server were the error occurs, I disabled the IIS discovery to fix the
problem.

Not sure how relevant is this for you, but I wanted to share my findings.
Regards,
Chris

I added an override prevent further alerts for this condition. How do I
disable the IIS discovery for a particular server?

[Chris Vico]

Go to Authoring mode,
Select "discovery",
reduce the scope to IIS related thinggy.

You'll find 3 interesting Discovery:
- Windows IIS Role Discovery Rule (Target Windows Server)
- Windows IIS Services Base Classes Discovery Rule (Target Windows Server)
- Windows IIS Role All component Discovery Rule (Target Windows Server)

On each of these, Right-Click > Override the Object Discovery > For a
specific object.

MAke sure that the object type you're adding are Computer.
