Ever get the following error?
“It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.”
And of course you don't want to spend all day going through the IIS MMC dialog boxes on a web server with a large number of applications. I put together a script to dump the script mappings which will tell you what the site is configured to run by looking at the ISAPI filter path for your script maps:
Option Explicit
Dim network
Set network = CreateObject("WScript.Network")
Dim wmiService
Set wmiService = GetObject("winmgmts:{authenticationLevel=pktPrivacy}\\" & _
network.ComputerName & "\root\microsoftiisv2")
Dim applicationPools
Set applicationPools = WMIService.ExecQuery("Select * From IIsApplicationPool " & _
"Where Name LIKE 'W3SVC/AppPools/%'")
WScript.Echo "Application Pool Name" & vbTab & "Application Name" & vbTab & _
"Extension" & vbTab & "Processor"
Dim applicationPool
For Each applicationPool in applicationPools
Dim applications
applicationPool.EnumAppsInPool applications
Dim index
For index = 0 to UBound(applications)
Dim applicationName
applicationName = CleanAppName(applications(index))
On Error Resume Next
Dim virtualDirectorySetting
Set virtualDirectorySetting = wmiService.Get("IIsWebVirtualDirSetting='" & _
applicationName & "'")
If Err.Number = 0 Then
Dim scriptMap
For Each scriptMap in virtualDirectorySetting.ScriptMaps
WScript.Echo applicationPool.Name & vbTab & ApplicationName & _
vbTab & ScriptMap.Extensions & vbTab & _
ScriptMap.ScriptProcessor
Next
Else
WScript.Echo ApplicationPool.Name & vbTab & ApplicationName & _
vbTab & "--" & vbTab & _
"Unable to locate application virtual directory."
End If
On Error GoTo 0
Next
Next
' Trims the leading /LM/ and trailing /
Function CleanAppName(applicationName)
If Len(applicationName)
The results can be opened in Excel and with the use of the handy Auto Filter feature you can narrow your scope and spot the problem in a lot less time than manually sniffing through.
