IIS , Scripting , IIS 6
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.

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.
' 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/" & _
' 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
' try not to be a CPU hog
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.
