Remotely check Windows firewall status
As part of my routine auditing process I wanted to check to ensure that the Windows firewall is enabled and set to use its domain profile on all of our Member servers.
Here’s a script to do just that
' Configuration.
'====================================================================
Dim strFirewallStatus, strComputer, arrComputers
arrComputers = Split("london,brisbane,perth,chicago", ",")
WScript.Echo "-------------------------------------------------------"
WScript.Echo Left("Computer Name" & Space(47),47) & "Status"
WScript.Echo "-------------------------------------------------------"
' Iterate through computers, showing status.
'====================================================================
For Each strComputer in arrComputers
' Required so we don't die on permission errors.
On Error Resume Next
Set objReg = GetObject( "winmgmts:{impersonationLevel" &_
"=impersonate}!\\" & strComputer & "\root\default:StdRegProv")
If err.number = 0 Then
objReg.GetDWORDValue &H80000002, "SYSTEM\CurrentControlSet\" &_
"Services\SharedAccess\Parameters\FirewallPolicy\" &_
"DomainProfile\", "EnableFirewall",dwValue
If dwValue <> 0 Then
strFirewallStatus = "Enabled"
Else
strFirewallStatus = "Disabled"
End If
WScript.Echo Left(strComputer & Space(47),47) & strFirewallStatus
Else
WScript.Echo strComputer & " - Error" & err.number & " : " &_
err.description
err.clear
End if
Next
You’ll need to make sure that you’ve got the relevant permissions on the target computers, otherwise you’ll just get errors.
