How to run IIS in 32 bit mode on 64 bit windows

I recently used the following KB from MS to try and run 32 bit IIS on my 64 bit windows OS.

The issue is that the ops team gave us a 64 bit server and Business Objects runs on 32 bit only. After following the KB article above, we can't even get a basic .txt file to display through IE. I keep getting the "Service Unavailable" error. I have attached the application log error as a text file.

Has anybody had any success running 32 bit IIS on a 64 bit Windows 2003 platform? If so...what am I missing here.

Try this?

Open a command prompt and navigate to the %systemdrive%\Inetpub\AdminScripts directory.

cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 “true”

I did that and rebooted...still not giving me "Service Unavailable". Same error as posted before in the event log. Also this on, however a separate team does the McAffee configuration.
Did the change on the IIS bit level cause the McAfee ISAPIstub.dll error or was that pre-existing?
If it was caused by it, then I suggest reverting the bit level back to it's previous setting.

You should have an error message in your application event log complaining about a specific ISAPI filter.  The problem is that you have some ISAPI dll either set to run 32bit on a 64bit web application or vice versa.

If you do not have applications requiring the specific filter you can comment it out from load.  The other method is to verify that you have the correct bit version of the ISAPI dll required.  Of course based on your error messages thus far it is not pointing to any specific ISAPI filter.

First verify the DLL you need to load is actually there.
You can then go into IIS metabase and 'comment' out the line where the filter is in question was referenced if you don't require it.  Good practice is to have a backup of your IIS metabase first and use an IIS metabase explorer as the file can be quite overwhelming.

An available browser can be found in the IIS resource kit.
