Changing WINS settings on client machines can be a pain when you have to move your WINS servers. This hack makes it easier.
If you are using WINS as a name-resolution method (typically in a mixed NT/2000 environment) and have to change your WINS serversfor example, when you install a new WINS serveryou have to reconfigure WINS settings on all your client computers. If you are using DHCP, you can configure the 044 WINS/NBNS Servers option on your DHCP servers to provide client computers with new WINS servers addresses, but this requires releasing and renewing DHCP leases on all your clients.
Here's another approach you can use. The following script changes the WINS server settings on client machines and is useful when you install new WINS servers and need to change your WINS server settings on workstations across the board. Note that the script also works on multihomed machines (machines that have two or more network adapters).
Type the following code into Notepad (with Word Wrap disabled) and save it with a .vbs extension as ChangeWINS.vbs:
Option Explicit
On Error Resume Next
Dim objLocator, objService, NIC
Dim strComputer, strUsername, strPassword
Dim strWINS1, strWINS2
Dim intErr
strComputer = "."
strUsername = "
strPassword = "
strWINS1 = "172.16.1.122"
strWINS2 = "172.16.1.132"
Set objLocator = CreateObject("WbemScripting.SWbemLocator")
Set objService = objLocator.ConnectServer(strComputer, "root/cimv2", & strUsername,
strPassword)
objService.Security_.impersonationlevel = 3
For Each NIC In objService.ExecQuery("Select * from Win32_NetworkAdapterConfiguration
Where IPEnabled=True")
WScript.Echo "Nic Index: " & NIC.index
WScript.Echo "Current Settings"
WScript.Echo "Primary Wins Server: " & NIC.WINSPrimaryServer
WScript.Echo "Secondary Wins Server: " & NIC.WINSSecondaryServer
intErr = NIC.SetWinsServer(strWINS1, strWINS2)
If intErr <> 0 Then Wscript.Echo "Error changing WINS"
Next
Set objService = Nothing
Set objLocator = Nothing
To run this hack, you first have to customize it. For example, if your primary WINS server is 10.0.0.15 and your secondary server is 10.0.0.16, change these lines:
strWINS1 = "172.16.1.122" strWINS2 = "172.16.1.132"
to this:
strWINS1 = "10.0.0.15" strWINS2 = "10.0.0.16"
Then, create a shortcut to the script and double-click on the shortcut to run the script. This will refresh your computer's WINS settings.
