Does anyone know how I can remotely use a batch/vb/powershell script to turn on a bunch of servers using the HP iLO and also the Dell DRAC??

You can.. and I have a powershell script that does just that (at least HP.)

You can use the HP CLI or send the Magic Packet.

whats your preference... the magic packet should work for both.

Both please, as this is a learning experience, I will have to see which one works best in our environment.  I am pretty sure Dell has a similar command line thing, do you know that one?

btw, magic packet is a new term for me, what is that?

Here is the Magic packet script. I will have to wait till tomorrow to get the CLI stuff.

It requires the MAC address but that should easy to get.
########################################################################################
param ($macString = $(throw 'mac address is required'),
       [switch]$verbose)
if($verbose){$verbosePreference = "continue"}
if($macString -notmatch ":")
{
    Write-Verbose "Converting $macstring to Mac Address"
    $macaddy = import-csv $table | ?{$_.Name -match $macString} | %{$_.Mac}
    Write-Verbose "Converted to $macaddy"
}
else
{
    $macaddy = $macString
}
 
$mac = $macaddy.split(':') | %{ [byte]('0x' + $_) }
 
if ($mac.Length -ne 6)
{
    throw 'mac address must be 6 hex numbers separated by :'
}
Write-Verbose "Creating UDP Packet"
$UDPclient = new-Object System.Net.Sockets.UdpClient
$UDPclient.Connect(([System.Net.IPAddress]::Broadcast),4000)
$packet = [byte[]](,0xFF * 6)
$packet += $mac * 16
Write-Verbose ([bitconverter]::tostring($packet))
[void] $UDPclient.Send($packet, $packet.Length)
Write-Verbose "Wake-On-Lan magic packet of length $($packet.Length) sent to $macString"

Here is my Invoke-iLOCommand.ps1 file. It requires CMDLets from nsoftware. If you dont want to use those you can use plink.exe

nSoftware
http://www.nsoftware.com/powershell/

Plink.exe
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Basically this will send any command you want to the iLO.
In your case
Invoke-iLOCommand.ps1 -cmd "Power On" -server x
# requires snapin Netcmdlets
# Invoke-iLOCommand
Param($cmd = $(throw '$CMD is Required'),
      $list,
      $server,
      $creds = $(Get-Credential),
      $filter = ".*"
      )
	function Ping-Server {
		Param([string]$srv)
		$pingresult = Get-WmiObject win32_pingstatus -f "address='$srv'"
		if($pingresult.statuscode -eq 0) {$true} else {$false}
	}
Write-Host
 
if(!$list -and !$Server){Write-Host "You must Provide a List of Servers or a Server" -fore Yellow}
 
if($list)
{
    if(Test-Path $list)
    {
        foreach($server in (get-Content $list))
        {
            if(Ping-Server $Server)
            {
                Write-Host " + Invoking Command:[$cmd] on Server:[$Server]" -Fore Green
                $result = Invoke-SSH -command $cmd -Server $server -Credential $creds -force 
                $result = $result | Foreach-Object{$_.Text.Split("`n")} | Where-Object{$_ -match $filter}
                $result
            }
            else
            {
                Write-Host "Ping of Server [$Server] Failed" -fore Red
            }
            Write-Host
        }
    }
    else
    {
        Write-Host "Invalid List File [$list]"  -fore Red
    }
}
 
if($server)
{
    if(Ping-Server $Server)
    {
        $result = Invoke-SSH -command $cmd -Server $server -Credential $creds -force 
        $result = $result | Foreach-Object{$_.Text.Split("`n")} | Where-Object{$_ -match $filter}
        $result
    }
    else
    {
        Write-Host "Ping of Server [$Server] Failed"  -fore Red
    }
}
Write-Host
