How to Discover Host Connection by PowerShell

The following sections describe the Host Connection by PowerShell discovery.

1. Prerequisite - Set up protocol credentials

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

   For credential information, see Supported Protocols.

2. Prerequisite - Configure PowerShell

   Before starting the discovery, ensure that PowerShell v2.0, 3.0, 4.0, 5.0, or 5.1 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 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.

3. 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 Data Flow Management section of the UCMDB Help.
