One of my servers has a large number of individual web sites on it, and each of these web sites has several server bindings for different IP addresses, Port Assignments, and Host Headers. As I continue to add more web sites on the server, it becomes increasingly difficult to keep track of all the details using the IIS user interface.

With that in mind, I wrote the following ADSI script which creates a text file that contains an itemized list of all server bindings on a server.

Option Explicit
On Error Resume Next

Dim objBaseNode, objChildNode
Dim objBindings, intBindings
Dim objFSO, objFile, strOutput

' get a base object
Set objBaseNode = GetObject("IIS://LOCALHOST/W3SVC")
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("ServerBindings.txt")

' check if if have an error ...
If (Err.Number <> 0) Then

    ' ... and output the error.
    strOutput = "Error " & Hex(Err.Number) & "("
    strOutput = strOutput & Err.Description & ") occurred."

' ... otherwise, continue processing.
Else
    ' loop through the child nodes
    For Each objChildNode In objBaseNode
        ' is this node for a web site?
        If objChildNode.class = "IIsWebServer" Then
            ' get the name of the node
            strOutput = strOutput & "LM/W3SVC/" & _
                objChildNode.Name
            ' get the server comment
            strOutput = strOutput & " (" & _
                objChildNode.ServerComment & ")" & vbCrLf
            ' get the bindings
            objBindings = objChildNode.ServerBindings
            ' loop through the bindings
            For intBindings = 0 To UBound(objBindings)
                strOutput = strOutput & vbTab & _
                    Chr(34) & objBindings(intBindings) & _
                    Chr(34) & vbCrLf
            Next
        End If
    ' try not to be a CPU hog
    Wscript.Sleep 10
    Next
End If

objFile.Write strOutput
objFile.Close

Set objBaseNode = Nothing
Set objFSO = Nothing

Hope this helps!

(Note: I had originally posted this information on a blog that I kept on http://weblogs.asp.net, but it makes more sense to post it here. [:)] )

Like many web programmers, I host several hobby web sites for fun. (They make a wonderful test bed for new code. ;-] )

And like many computer enthusiasts, I sometimes change my ISP for one reason or another. If you are hosting web sites in a similar situation, I'm sure that you can identify the pain of trying to manually update each old IP address to your new IP address. This situation can be made even more difficult when any number of your web sites are using several host headers because the user interface for the IIS administration tool only lists the first host header. This means that you have to manually view the properties for every site just to locate the IP addresses that you are required to change.

Well, I'm a big believer in replacing any repetitive task with code when it is possible, and a recent change of ISP provided just the right level of inspiration for me to write a simple Active Directory Service Interfaces (ADSI) script that locates IP addresses that have to be changed and updates them to their new values.

To use the example script, I would first suggest that you make a backup copy of your metabase. (The script works fine, but it is always better to have a backup. ;-] ) As soon as your metabase has been backed up, copy the example script into notepad or some other text editor, update the old and new IP addresses that are defined as constants, and then run the script.

Option Explicit
On Error Resume Next
 
Dim objIIS
Dim objSite
Dim varBindings
Dim intBindings
Dim blnChanged
 
Const strOldIP = "10.0.0.1"
Const strNewIP = "192.168.0.1"
 
Set objIIS = GetObject("IIS://LOCALHOST/W3SVC")
 
If (Err <> 0) Then
  WScript.Echo "Error " & Hex(Err.Number) & "(" & _
    Err.Description & ") occurred."
  WScript.Quit
Else
  For Each objSite In objIIS
    blnChanged = False
    If objSite.class = "IIsWebServer" Then
      varBindings = objSite.ServerBindings
      For intBindings = 0 To UBound(varBindings)
        If InStr(varBindings(intBindings),strOldIP) Then
          blnChanged = True
          varBindings(intBindings) = Replace(varBindings(intBindings),strOldIP,strNewIP)
        End If
      Next
    End If
    If blnChanged = True Then
      objSite.ServerBindings = varBindings      
      objSite.Setinfo
    End If
  Next
End If
MsgBox "Finished!"

That's all for now. Happy coding!

Note: I originally wrote the following script for a friend, but as every good programmer often does, I kept the script around because I realized that it could come in handy. I've found myself using the script quite often with several of the servers that I manage, so I thought that I'd share it here.

When managing a large web server with dozens of web sites, it's hard to keep track of all the host headers that you have configured in your settings. With that in mind, I wrote the following script that lists the host headers that are assigned on an IIS web server. To use the example script, copy the script into notepad or some other text editor, save it to your server as "HostHeaders.vbs", and then double-click the script to run it. The script will create a text file named "HostHeaders.txt" that contains all the host headers listed by site for your server.

Option Explicit

Dim objBaseNode, objChildNode
Dim objBindings, intBindings
Dim objFSO, objFile, strOutput

' get a base object
Set objBaseNode = GetObject("IIS://LOCALHOST/W3SVC")
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("HostHeaders.txt")

' check if we have an error ...
If (Err.Number <> 0) Then

    ' ... and output the error.
    strOutput = "Error " & Hex(Err.Number) & "("
    strOutput = strOutput & Err.Description & ") occurred."

' ... otherwise, continue processing.
Else

    ' loop through the child nodes
    For Each objChildNode In objBaseNode

        ' is this node for a web site?
        If objChildNode.class = "IIsWebServer" Then

            ' get the name of the node
            strOutput = strOutput & "LM/W3SVC/" & _
                objChildNode.Name

            ' get the server comment
            strOutput = strOutput & " (" & _
                objChildNode.ServerComment & ")" & vbCrLf
            ' get the bindings
            objBindings = objChildNode.ServerBindings
            ' loop through the bindings
            For intBindings = 0 To UBound(objBindings)
                strOutput = strOutput & vbTab & _
                    Chr(34) & objBindings(intBindings) & _
                    Chr(34) & vbCrLf
            Next
        End If
    ' try not to be a CPU hog
    Wscript.Sleep 10
    Next
End If
objFile.Write strOutput
objFile.Close
Set objBaseNode = Nothing
Set objFSO = Nothing

If you feel adventurous, you could easily modify the script to return the text in a tab-separated or comma-separated format.

Enjoy!
