Hack 40 Change WINS for All Enabled Adapters
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).
The Code
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
Running the Hack
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.
