jan jan Getting the hang of it Registered: 2004-07-07 Posts: 66	Hi, I'm looking for a script where I can change the DNS settings on my servers (they have static IP and I know how to change suffix), due to new DNS servers. Is there anybody how knows how to do that. My servers have different network vendors, so it has to be able to get the current LAN-card in use. Thanks Jan

To get you going, here is a quick and dirty attempt... make sure to paste the UDFs to the bottom of your script.

Untested

Code:

$newdnsservers="nnn.nnn.nnn.nnn,mmm.mmm.mmm.mmm"
$olddnsservers="xxx.xxx.xxx.xxx,yyy.yyy.yyy.yyy"
$serverlist=  ;array of computernames...list them manually here, use a file, or query AD/NT

for each $server in $serverlist 
  For each $netconnection in Enumnetworkconnections(1,$server)
    ? $Server + " : " + $netconnection + " : "
    $mac=split($netconnection,",")[1]
    if GetIPOptions("DNSServers",$Server,$mac)=$olddnsservers
      $RC=setipoptions("DNSServers",$newdnsservers,$server,$mac) 
      @serror
    endif  
  next
next

To be honest though, all you need is a collection of mac addresses, and I would bet there are a couple of UDFs to do that. Also see NICInfo() http://www.kixtart.org/forums/ubbthreads.php?ubb=showflat&Board=7&Number=150839 _________________________ (... better days ahead)

Allen Allen KiX Supporter Registered: 2003-04-19 Posts: 4572 Loc: USA	Digging around some... and sure enough there are a number of variations of the GetMAC() in this one thread: http://www.kixtart.org/forums/ubbthreads.php?ubb=showflat&Number=84616&page=4#Post84616 I really liked Radimus's version (very bottom), but Jooel's UDF should work for the purpose of fixing the example script: Code: $newdnsservers="nnn.nnn.nnn.nnn,mmm.mmm.mmm.mmm" $olddnsservers="xxx.xxx.xxx.xxx,yyy.yyy.yyy.yyy" $serverlist= ;array of computernames...list them manually here, use a file, or query AD/NT for each $server in $serverlist For each $mac in GetMAC($Server) ? $Server + " : " + $mac+ " : " if GetIPOptions("DNSServers",$Server,$mac)=$olddnsservers $RC=setipoptions("DNSServers",$newdnsservers,$server,$mac) @serror endif next next _________________________ (... better days ahead)
