Reply To: Services using Domain admin account

You’re overwriting ServerList.htm every time through the loop with that call to Out-File. What you’re probably looking to do is something more like this (moving the calls to ConvertTo-Html and Out-File outside the loop):

$head = @'
<style>
BODY{background-color:#012456;}
H2{color:White;}
TABLE{border-width: 2px;border-style: solid;border-color:white;border-collapse: collapse;}
TH{border-width: 2px;padding: 10px;border-style: solid;border-color:white;color:#FFFFFF;}
TD{border-width: 2px;padding: 10px;border-style: solid;border-color: white;color:white}
</style>
'@

$ifeverything_ok = $true

Get-Content C:\Allwindows.csv |
ForEach-Object {
    $comp = $_
    try
    {
        $ErrorActionPreference = "Stop"
        
        $properties = @(
            @{Expression={$_.systemName};Label = "Server Name"},
            @{Expression={$_.DisplayName};Label = "Service Name"},
            @{Expression={$_.Name};Label = "Service"},
            @{Expression= {$_.StartName};Label = "Account"},
            'State'
        )

        Get-WmiObject win32_service -ComputerName $comp -filter "StartName Like '%Administrator%'" |
        Select-Object -Property $Properties
        
        $comp | Out-File C:\Temp\Logs.txt -Append -Encoding ascii

    }
    Catch [system.exception]
    {
        $ifeverything_ok = $false
        $comp | Out-File C:\Temp\Logs.txt -Append -encoding ASCII
        Add-Content -Value $_.Exception -Path C:\Temp\Logs.txt
    }
} |
ConvertTo-Html -Head $head -Body "<H2>Service Accounts Running As Domain Administrator</H2>" |
Out-File C:\ServerList.htm

Invoke-Expression C:\ServerList.htm

On a side note, this script doesn’t actually identify services running as a Domain Admin account (which would imply you should be checking for group membership). It just looks for services running as any account with “Administrator” in the name.
