WMIにはいくつか面白いオブジェクトがあるので使ってみる。
Win32_PingStatus : 指定されたアドレスにPingを飛ばして詳細な結果オブジェクトを返す
試しに www.google.com にPingを投げてみるには、
PS C:\Users\imksoo> $ping_status = Get-WmiObject -Namespace "root\cimv2" -Query "SELECT * FROM Win32_PingStatus WHERE Address='www.google.com'"
PS C:\Users\imksoo> $ping_status | Get-Member

1秒おきにPingを打ち続けるとかであれば、以下の様にFormat-Tableで現在時刻を付与しながら表示してあげると、後々整形しやすいかと。
(ExPingもどきを目指すのであれば、タイムアウト値とかをGet-WmiObjectコマンドレットでPingStatusオブジェクトを作るときに渡しておくとかでしょうか)
PS C:\Users\imksoo> while ( -not (Start-Sleep 1) ) {
>> $ping_status = Get-WmiObject -Namespace "root\cimv2" -Query "SELECT * FROM Win32_PingStatus WHERE Address='www.googl
