# Specify the location of the request files
$csrdir = "C:\Certs\Requests\"

$files = Get-ChildItem $csrdir
$csrs = $files | ? {$_.extension -eq ".csr"}

# Parameters
$template = "WebServer" # must always use concatenated name format
$CA = "MyCAServer.mydomain.com\MyCAName"

foreach ($csr in $csrs)
{
    write-host "Requesting certificate $csr ..."
    $basename = $csr.basename
    # Specify the command line parameters for certreq.exe
    $parameters = "-config $CA -submit -attrib CertificateTemplate:$template " `
    + "$csrdir" + "$basename" + ".csr " +  "$csrdir" + "$basename" + ".cer " `
    +  "$csrdir" + "$basename" + ".p7b"
    # Start certreq.exe and pass in the parameters
    $request = [System.Diagnostics.Process]::Start( "certreq",$parameters )
    $request.WaitForExit()
    write-host "Finished request $csr"
    #sleep 10
} # end foreach
