How to Discover Host Connection by PowerShell

The following sections describe the Host Connection by PowerShell discovery.

Prerequisite - Set up protocol credentials

The Host Connection by PowerShell discovery solution is based on the PowerShell protocol.

For credential information, see Supported Protocols.
Prerequisite - Configure PowerShell
Before starting the discovery, ensure that PowerShell v2.0 or later is installed and configured on the Data Flow Probe machine. To access the installation files, see http://support.microsoft.com/kb/968929).
1. Enable PowerShell remoting:
  - Launch PowerShell v2.0 or later as an administrator.
  - Run the Enable-PSRemoting cmdlet. This starts the WinRM service and sets the startup type to Automatic, enables a firewall exception for WS-Management communications, and creates a listener to accept requests on any IP address.
    
    Note To enable PowerShell remoting on all computers in your domain, in Domain Group Policy: Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Remote Management (WinRM) > \WinRM Service, select Allow automatic configuration of listeners.
2. To trust all hosts, run the following from the command line:
```
Set-Item WSMan:\localhost\Client\TrustedHosts * 
```
  To trust only restricted IP addresses, specify the addresses in place of the asterisk (*).
3. Restart WinRM by running the following from the command line:
```
restart-Service winrm
```
  Note By default, WinRM uses Kerberos for authentication. To configure WinRM for https, see http://support.microsoft.com/kb/2019527.
Run the discovery
1. Run the Range IPs by ICMP job.
2. Run the Host Connection by PowerShell job.
For details on running jobs, see "Module/Job-Based Discovery" in the HPE Universal CMDB Data Flow Management Guide.
