[Zope] IIS - No pcgi info file given error

I'm trying to configure Zope and IIS to live together with PCGI. I found a few posts on this and installed the pgci executable and zope.pcgi config file in the IIS scripts directory. Then, I modified the registry for my Zope install. I am getting the following error: Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later The trace is No pcgi info file given! pcgi-wrapper-version 2.0a4 I can't find anything on this error. Any help appreciated (and I'll document it), Josh
