Audt Drive Mappings - Group Policy Objects with Powershell

We have bunch of GPOs that perform drive mappings
Unfortunately another team normal does the site work.

so after a little while with servers moving all over the place servers disappear but GPO still had mappings and groups . RAGE

so a bit of powershell to check all the paths

diving into the get-gpo was interesting.

got stumped on test-path when access is denied for a little while until worked out the errorvariable was the way around it.

powershell html table color

Came across some code to change arrays into some nice html code.
has the ability to colour code cells.

#
# $finalrepinfo is array
#
$html = $finalRepInfo|ConvertTo-Html -Fragment
 
$xml = [xml]$html

$attr = $xml.CreateAttribute("id")
$attr.Value='diskTbl'
$xml.table.Attributes.Append($attr)


$rows=$xml.table.selectNodes('//tr')
for($i=1;$i -lt $rows.count; $i++){
    $value=$rows.Item($i).LastChild.'#text'
    if($value -ne $null){
       $attr=$xml.CreateAttribute('style')
       $attr.Value='background-color: red;'
       [void]$rows.Item($i).Attributes.Append($attr)
    }
  
    else {
       $value
       $attr=$xml.CreateAttribute('style')
       $attr.Value='background-color: green;'
       [void]$rows.Item($i).Attributes.Append($attr)
    }
}

#embed a CSS stylesheet in the html header
$html=$xml.OuterXml|Out-String
$style='<style type=text/css>#diskTbl { background-color: white; }
td, th { border:1px solid black; border-collapse:collapse; }
th { color:white; background-color:black; }
table, tr, td, th { padding: 2px; margin: 0px } table { margin-left:50px; }</style>'

ConvertTo-Html -head $style -body $html -Title "Replication Report"|Out-File ReplicationReport.htm

Microsoft Forefront Eventlog | Powershell

thru complex number of reasons... need to monitor forefront via eventlogs - dont have centralised reporting.

1.could of setup alerts on each box to email when a virus detections
2.powershell to check eventlogs and do stuff with it.

had issue with eventlog culture on non powershell4 box.

#
# Virus Detections Last 1 days
#

$LogEntries =@()
$daysAgo = (get-date) - (new-timespan -day 1)

# BugFix for PS3 and anything other than en-us
$orgCulture = Get-Culture
[System.Threading.Thread]::CurrentThread.CurrentCulture = New-Object "System.Globalization.CultureInfo" "en-US"

#
# Target
#
$ou='OU=MOE Servers,DC=lc,DC=local'
$computers=Get-ADComputer -Filter * -SearchBase $ou


foreach ($server in $computers) {
$report=Get-WinEvent -FilterHashtable @{logname='system'; id=1006; ProviderName='FCSAM';StartTime=$daysAgo} -computername $server.dnshostname -ErrorAction SilentlyContinue

    if ($report){
    foreach ($panda in $report){
        $Obj = New-Object -TypeName PsObject
        $Obj | Add-Member -membertype noteproperty -name Server -value ($server.DNSHostName)
        $Obj | Add-Member -membertype noteproperty -name TimeCreated -value ($panda.timecreated)

            foreach ($jeff in (($panda.message).Split("`r"))){
            if ($jeff -match "Name:"){$output=$jeff}
            if ($jeff -match "Severity:"){$output+=$jeff}
             }
        $Obj | Add-Member -membertype noteproperty -name Message -value ($output.Trim())
        $LogEntries += $Obj
    }
#Clear 
$report=$null
$output=$null
}

}

#
# Switch back to Aus
#
[System.Threading.Thread]::CurrentThread.CurrentCulture = New-Object "System.Globalization.CultureInfo" "en-AU"

$LogEntries | sort timecreated -Descending

#
# then do stuff like export to webserver or..
