无法使用Powershell从远程服务器获取IIS状态

Question

I am trying to fetch IIS status from remote server using powershell. I have used command Get-Service but i don't recieve any output from this command. Below is my code block.

$pass='pass'|ConvertTo-SecureString -AsPlainText -Force;
$Credentials =  New-Object   
System.Management.Automation.PsCredential("user",$pass);
$Service=invoke-command -computername "server" -credential $Credentials - 
scriptblock {Get-Service|Where-Object Name -eq 'IISADMIN'}
if($Service.Status -eq 'Running')
{
write-host "IIS Running"
}
else
{
 throw "IIS not running or Not installed"

}

Answer 1

I Checked your code and did not see any problem with it, Did you checked the service exists locally using Get-Service or Service Manager?

Anyway you don't have to use Invoke-Command for this, you can use the built in -ComputerName parameter of the Get-Service cmdlet,

And if you need to provide credentials, you can use WMI:

$Credential = New-Object System.Management.Automation.PsCredential($username, $encrypted)
$Service = Get-WmiObject -Class win32_service -ComputerName Server -Filter 'Name = "W3SVC"' -Credential $Credentials

Answer 2

Try using a WMI call instead, I have found it far more reliable when working with remote servers.

$Service = Get-WmiObject -Computername $computer -Credential $credentials Win32_service -ErrorAction Continue | Where {$_.Name -eq 'IISADMIN'}
