I had installed 9i AS Infrastructure(9.0.2 Rel 2) on Win2000 . I had checked connecting to http server after installation(for eg. http://appstest:7777). Then, during 9i Application Server installation I was prompted for Hostname and port number in the Single sign on screen. I had given the hostname and the port number 7777(which is the default httpserver port no.) I get an error: "An error occurred while verifying your hostname and port no:" I'm unable to proceed the installation process.
