Brian,
Here's a snippet of code I use to browse the network and check up on NAV. I'm sure you can adapt...
code:
break on
Call "C:\KiX4.02\UDF\netview.kix"
;Get VPDate from NAV primary
$computer ="FFRAS"
GoSub CurrentPatternName
$NAVMaster = $CurrentPatternName
$currentbuildver = "7.61.00.932"
$netview = netview("@LDOMAIN")
if @error = 0
  for each $computer in $netview
    if $computer <> "FFCDTOWER" ;darn Linux
      $computer
      if KeyExist("\\"+ $computer +"\HKLM\SOFTWARE" )
        $RC=WriteProfileString("C:\KiX4.02\NAVStatus.ini", "$computer", "LastSeen", "@Date")
        Gosub FindMore
      else
        ?
      endif
    endif
  next
endif

? "That all for this go around"
Get $_
Exit 1
p.s It uses Shawn's NetView() UDF and I left out the subroutines to keep it short as it is not really relevant to your task.
