Function Invoke-Ping
{
<#
.SYNOPSIS
Ping or test connectivity to systems in parallel
.DESCRIPTION
Ping or test connectivity to systems in parallel
Default action will run a ping against systems
If Quiet parameter is specified, we return an array of systems that responded
If Detail parameter is specified, we test WSMan, RemoteReg, RPC, RDP and/or SMB
.PARAMETER ComputerName
One or more computers to test
.PARAMETER Quiet
If specified, only return addresses that responded to Test-Connection
.PARAMETER Detail
Include one or more additional tests as specified:
WSMan via Test-WSMan
RemoteReg via Microsoft.Win32.RegistryKey
RPC via WMI
RDP via port 3389
SMB via \\ComputerName\C$
* All tests
.PARAMETER Timeout
Time in seconds before we attempt to dispose an individual query. Default is 20
.PARAMETER Throttle
Throttle query to this many parallel runspaces. Default is 100.
.PARAMETER NoCloseOnTimeout
Do not dispose of timed out tasks or attempt to close the runspace if threads have timed out
This will prevent the script from hanging in certain situations where threads become non-responsive, at the expense of leaking memory within the PowerShell host.
.EXAMPLE
Invoke-Ping Server1, Server2, Server3 -Detail *
# Check for WSMan, Remote Registry, Remote RPC, RDP, and SMB (via C$) connectivity against 3 machines
.EXAMPLE
$Computers | Invoke-Ping
# Ping computers in $Computers in parallel
.EXAMPLE
$Responding = $Computers | Invoke-Ping -Quiet
# Create a list of computers that successfully responded to Test-Connection
