Hi,

I’m trying to collect all the patches from list of servers which is in notepad. The command i use is **Get-Hotfix -computername (Get-Content C:\users\ssubram4\Desktop\Patching\All\_2016.txt)**

In the file All\_2016.txt, i have 250 servers.If the 10th server is unavailable, iam able to get the hotfix upto 9th server only and i got the below error.

Get-Hotfix : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)  
At line:1 char:1

```auto

```

- CategoryInfo : NotSpecified: (🙂 [Get-HotFix], COMException
- FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Microsoft.PowerShell.Commands.GetHotFixCom

So you need to check the availability of each single server before you query the hotfixes. You can do this in a loop with [Test-Connection](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/test-connection?view=powershell-5.1).

```
Test-Connection -ComputerName "ComputerName" -Count 1 Quiet
```

… returns a $true if the target computer is available and a $false if not. 😉

You need to use try/catch block or ping the server before executing the command…

[pre]

$Servers = Get-Content -Path C:\users\ssubram4\Desktop\Patching\All\_2016.txt

foreach ($Server in $Servers)  
{  
Try  
{  
Get-HotFix -ComputerName $Server  
}  
catch  
{  
#Continue  
}  
}

[/pre]

or

[pre]

$Servers = Get-Content -Path C:\users\ssubram4\Desktop\Patching\All\_2016.txt

foreach ($Server in $Servers)  
{  
if (Test-Connection -ComputerName $Server -Count 1 -Quiet)  
{  
Get-HotFix -ComputerName $Server  
}  
}

[/pre]
