Aghghhghgh! What a nightmare! It was working yesterday and now what's going on? We have a development webserver at work that uses IIS 5 and Tomcat 4 to display standard web content and run some Java servlets. For some reason after rebooting the servlets can no longer be accessed through port 80, but only through port 8080 (i.e. apache's standard port not IIS's). I've been through all the documentation I can find on the subject, checked all the setup options I can and still nothing. The only thing I can think of is that the filter has gone down for some reason (Big green arrow is still there though). It's very frustrating. Has anyone out there had and solved the same problem? Ian
