   $share="\\Server\Share"
   $drvlist=(Get-PSDrive -PSProvider filesystem).Name
   Foreach ($drvletter in "DEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray()) {
       If ($drvlist -notcontains $drvletter) {
           $drv=New-PSDrive -PSProvider filesystem -Name $drvletter -Root $share
           break
       }
   }
