I am trying to configure MS ISA Server on W2K Advanced Server in StandAlone Mode. I have a NT 4.0 server running Weblogic Tengah Server and the web application is java based. From an external web client the initial web page comes up but when you login to the application with user ID and password, the application doesn't come up and eventually you will get an error stating the server is busy. We traced the ports the application uses and know that ports 3301, 3302, 3303, and 3304 are used by the application. So far we have been unsuccessful in configuring the ISA server to allow these ports or the application does a redirect to these ports and the ISA server doesn't know how to handle this. Any suggestions? Brenda Morgan
