| Name | Platform | Version | Protocol | Discovery type | Pattern \(or probe if indicated\) |
|---|---|---|---|---|---|
| Microsoft Active Directory Domain Services | Windows | 13, 30, 31, 44, 47, 52, 56, 69 | WMI WinRM | Top-down | Active Directory Service pattern |
| [Microsoft server \(as a Microsoft Exchange component\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/itom-visibility/r-ExchangeClientAccessServer.md) | Windows | 2003, 2007, 2010, 2013, 2016 | WMI WinRM | Horizontal and top-down | ExchangeFrontEndServer On Windows; PatternExchangeBackEndServer On Windows pattern |
| [HUB Transport Server \(as a Microsoft Exchange component\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/itom-visibility/r-ExchangeHub.md) | Windows | 2003, 2007, 2010, 2013, 2016 | WMI WinRM | Horizontal and top-down | Hub Transport Server On Windows pattern |
| Client Access Server \(CAS\) \(as a Microsoft Exchange component\) | Windows | 2003, 2007, 2010, 2013, 2016 | WMI WinRM | Horizontal and top-down | CAS On Windows pattern |
| Symptom | Cause | Solution |
|---|---|---|
| Discovery failed. The discovery log displays the message that starts with the following text: You must have the Exchange Common Commands PowerShell Snapin installed to use this script. | The indication sections of the pattern fail, because the user does not have permissions for running PowerShell commands. | Make sure that you provided a user with permissions to run PowerShell commands on servers that host Microsoft Exchange Server components, for example, CAS. |
| Discovery failed. The discovery log displays the error message that starts with the following text:\[servername.destination.com\] Connecting to remote server failed with the following error message: The WinRM client can not process the request. The authentication mechanism requested by the client is not supported by the server or unencrypted traffic is disabled in the service configuration. Verify the unencrypted traffic setting in the service configuration or specify one of the authentication mechanisms supported by the server. | The indication sections of the pattern fail, because the MID Server is not configured as a trusted host on the component you are discovering. | Add the MID Server to the list of trusted hosts on all hosts that you want to discover. |
| The application service map is very large, because it includes connections to all Outlook clients. | \(In deployments using Microsoft Exchange Server 2007, 2010 or 2013\), Service Mapping created connections using traffic-based discovery, which traces all open connections, instead of using PowerShell commands. | Make sure that you provided a user with permissions to run PowerShell commands on servers that host Microsoft Exchange Server components, for example, CAS. |
