NetWare Web Manager

I get the following error when trying to start Web Manager in one of my NetWare 5.1 servers: “Security must be on or off when specified in admin config file”. This comes up after the service says that it is listening on port 2200 which is normal. Then the error comes up and the service does not start. I tried reinstalling this service without overwriting files (so that I don’t have to re-install Service Pack 5) and that did not work. I was wondering if anybody has any suggestions before I overwrite my current files with a re-install and have to re-install service pack 5 on this server as well.
