# Microsoft IIS server discovery

Discovery identifies and classifies information about Microsoft IIS servers.

## Prerequisites

Install IIS Management Scripts and Tools on a Microsoft IIS Server.

## Credentials

Configure these credentials:

-   [Applicative credentials](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-security/applicative-creds.md)
-   [Windows credentials](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-security/r_WindowsCredentialsForm.md)

## Classifier, pattern, and probe

**Note:** For information on Probe to Pattern migration see the knowledge article [KB0694477](https://support.servicenow.com/kb_view.do?sysparm_article=KB0694477).

Discovery uses these classifiers, probes, and patterns for IIS discovery:

<table id="table_fzd_2yv_jz"><thead><tr><th>

-   Windows - Get IIS Information\*

</td><td>

</td></tr></tbody>
</table>\*Probes inactive on new instances.

To use patterns, verify that the correct pattern is specified in the horizontal pattern probe on the classifier. See [Add the Horizontal Pattern probe to a classifier](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/c-UsingPatternsForHorizontalDiscovery.md) for instructions.

## Data collected by Discovery for IIS Web Server

The following data is collected in the IIS Web Server \[cmdb\_ci\_microsoft\_iis\_web\_server\] table.

|Label|Field name|
|-----|----------|
|Name|name|
|Version|version|
|Type\*|type|
|Running process command|running\_process\_command|
|Running process key parameters|running\_process\_key\_parameters|

\*The Type is always IIS.

The following data is collected in the Web site \[cmdb\_ci\_web\_site\] table.

|Label|Field name|Source|
|-----|----------|------|
|Name|name|wmi|
|TCP Port|tcp\_port|wmi|

## Connections found by Service Mapping during top-down discovery

When top-down discovery reaches an IIS server, Service Mapping identifies the specific website and application or virtual directory serving the entry point, not just the IIS server itself. Service Mapping creates a connection from the entry point to the matching IIS Virtual Directory \[cmdb\_ci\_iisdirectory\] CI. The resulting service map shows the application running on IIS rather than a generic host-level node.
