powershell-2.0 - Ping in startup script

Question

Can ping command be used in a startup script to check connectivity to a network server ? Powershell startup script:

$Ping=new-object System.Net.NetworkInformation.Ping
$Reply=$ping.send("MyServer01")
if ($Reply.status() -eq "Success")
{
Perform operations
}
Else
{Perform other operations}

Rightnow, the $reply is blank during startup script execution but has values if I run after logged in.

Thanks.

Test-Connection 应该可以正常工作，但它不返回字符串“True”，而是返回布尔值 $True。所以：

if (Test-Connection "MyServer01" -Quiet) {
    Some-Command
} else {
    Other-Command
}

这在我的盒子（W2K3、Powershell 2、.NET 4.5）上运行良好。

PS：如果你只是运行cmd, ping MyServer01，它会工作吗？
