I want to modify the dns search list in the registry on a 100 plus vista enterprise machine.

I know it is in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Does any one have a script I could double click and merge to the registry?
The users of these machines are all technically inclined and it will be a case of placing the file on a network share they could all click and add to their machines.

Something along the lines of


Any help will be greatly appreciated

Try this script.

' This code will change the DNS suffix search order
' to "mycompany.com" followed by "east.mycompany.com"
strComputer = "."
arrNewDNSSuffixOrder = Array("mycompany.com", "east.mycompany.com")
' --------- END CONFIGURATION ------
Set objWMIService = GetObject("winmgmts:" _
 & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set nics = objWMIService.ExecQuery _
 ("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
Set Network = objWMIService.Get("Win32_NetworkAdapterConfiguration")
' now set the new DNS suffix search order
SetSuffixes = _
If SetSuffixes = 0 Then
  WScript.Echo "Success! Replaced DNS domain suffix search order."
ElseIf SetSuffixes = 1 Then
  WScript.Echo "Success! Replaced DNS domain suffix search order. Please reboot."
  WScript.Echo "Error! Unable to replace DNS domain suffix search order list."
End If

DB you know you can set this with Group Policy, right? Or are you wanting to add entries onto an existing list?

I have a 2000 SP4 AD where do you think I could start.

Step by step instructions will be helpful these migration process is getting the better of me .Is there an adm file you have or something really straight forward.

Lots of thanks

The policy can only be applied to XP and above, but that shouldn't mean we can't run it on your current domain, you just need to get the template on there.

The policy we'd be looking at is built into both Vista and XP. If you could install the Group Policy Management Console onto an XP system (or 2003 server) you should be able to set it and it will upload the necessary templates to your DCs.

It hides under:

Computer Configuration / Administrative Templates / Network / DNS Client

You would add the suffixes as a comma delimited list into the "DNS Suffix Search List" policy.
