Hi

All of a sudden when running a script to get server diskspace I get the following error:


Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At H:\Scripts\Get-Diskspace.ps1:8 char:5
+ gwmi  <<<< -query "SELECT SystemName,Caption,VolumeName,Size,Freespace FROM win32_logicaldisk WHERE DriveType=3" -com
puter $Servers |


Here's the Script:

#Gets diskspace from a given list and outputs to a csv file.

Cls
$Results = Read-host "Where do you want to save the file? (name and path please)"

$list = Read-Host "Enter filename of server list"
$Servers = (gc $list)
Write-Host "Please wait.  This may take some time. I am checking disk space on $Servers"

gwmi -query "SELECT SystemName,Caption,VolumeName,Size,Freespace FROM win32_logicaldisk WHERE DriveType=3" -computer $Servers |
Select-Object SystemName,Caption,VolumeName,@{Name="Size(GB)"; Expression={"{0:N2}" -f ($_.Size/1GB)}},@{Name="Freespace(GB)"; Expression={"{0:N2}" -f ($_.Freespace/1GB)}}, @{n="% Free";e={"{0:P2}" -f ([long]$_.FreeSpace/[long]$_.Size)}} |
sort "% Free" |
export-csv $Results

Write-Host "Finished. Your results are stored in $Results"


The script hasn't changed, and if I amend the script to point to just one server It works fine.  Could anyone see why this may be as I'm really stuck!

Thanks

For some reason, it can't contact the WMI service on one of remote machines in $servers variable. Most likely one of your servers is offline. You could check with WBEMtest to exclude PowersHell as the cause of the problem. Also, you should check the availability of the servers (filter only alive ones) before you run get-wmiobject. You could find more details here:

Thanks Aleksandar, i'll check out the links.

Just to re-iterate though, I can query WMI on each server if I only one server at a time. The issuue seems to be apparent when querying servers stored in an array.
