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 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.

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.
