在powershell中执行脚本时出错WSUS GetUpdate（）
我执行了一个Powershell脚本，但是出现错误
脚本
[datetime]$dataIni = "2017/01/01"
[datetime]$dataFim = "2017/01/20"
$serverWsus = "server1"
[void]
$wsus =[Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($serverWsus,$False,8530)
Write-Progress -Activity 'Getting updates...' -PercentComplete 0
$updatesneeded = $wsus.GetUpdate() | ? {($_.CreationDate -gt
[datetime]$dateFirst -and
$_.CreationDate -lt [datetime]$dateLast) -and
($_.Title -notmatch "Itanium" -and
$_.Title -match "Windows Server 2008 x64" -and
$_.UpdateClassificationTitle -eq "Security Updates")}
$i = 0
$total = $updatesneeded.Count
foreach ($update in $updatesneeded)
{
Write-Progress -Activity 'Approving updates...' -Status "%Complete" -
PercentComplete (($i/$total) * 100)
Approve-WsusUpdate -Update $update -Action Install -TargetGroupName 'enviroment'
$i++
}
Write-Host "Updates approved: $total" -ForegroundColor Yellow
错误
