Set up MID Servers to use PowerShell

Configure MID Servers in your organization to use PowerShell for horizontal and top-down discovery of Windows servers.

Before you begin

Role required: admin

Note:

This is enabled by default.

PowerShell version 2.0 is not supported, therefore it is recommended to upgrade to a higher version. If the MID Server detects that it has version 2.0, it may work partially. The MID Server creates a record in the mid_server issue table with the following message: PowerShell version 2 is deprecated. Upgrading PowerShell to version 5 is recommended.

Procedure

1. Download PowerShell and install it on each MID Server configured to discover Windows computers.
   If a compatible PowerShell is available on the Host, you don’t need to do anything else.
2. Determine which credentials MID Servers use for PowerShell.
   • To discover Windows computers using credentials from the credentials table, set the mid.powershell.use_credentials parameter to true. Using credentials form the credentials table is the default behavior when PowerShell is enabled.
   • To force Discovery and Service Mapping to use the credentials of the MID Server service user, set the mid.powershell.use_credentials parameter to false on the MID Server. The MID Server service must have domain admin credentials to have access to the Windows machines in the domain.
3. Optional: If necessary, configure advanced parameters for PowerShell and PowerShell Remoting on each MID Server separately.
   Although you can disable PowerShell by changing the mid.use_powershell and mid.sa.prefer_powershell, this method is deprecated and should not be used.
