[Zope] Could not lock database file

Hi, I am setting up pcgi with IIS. I got the following error: Zope Error zope has encountered an error while publishing this resuource exceptions.ImportError (,'Could not locak the database file. There must be \012another proccess that has opened the file.\012 ') I had this message before also, when I test with a test mechine. But that was my mistake that I forget to put the -p "D:\zope\zope.pcgi" when start the zope server. After I put this in, it work perfectly. However, this time, I did make this argument when start up the server. I am still can make it work. Can anyone give me idea? Kwan
