ArcIMS 4.0.1 migration from win2k to win3k

We are a small local government IT shop.? We require assistance moving our public ArcGIS [ArcIMS 4.0.1] server from a Windows 2000 server to a Windows 2003 server.? The purpose of the migration is to reduce security exposure on newer operating system.? ? The Windows 2000 server is working properly and will not be modified. The Win2003 server is running aother production application for us today.? It has IIS dedicated to supporting a public documents server.? The hit rate on the IIS is very low. We prefer to utilize Apache 2.2.10. Tomcat 6.0.18 and? Java SDK 1.4.0 but can consider other versions or IIS using ports that don't interfere with the production application.? Our license is only for ArcIMS 4.0.1 so that must remain.? We have loaded and attempted to configure Apache/Tomcat without success.. Presently the aboard the Win2003 server ArcIMS diagnostics fail indicating that? ? (/servlet/[login to view URL]) is not available.? ? Our assumption is this is an integration issue.
