Errors After CF8 Distributed Config Attempt

We have a server running multiple CF8 sites, as well as an ASP site, all of which were working fine. We configured a new web server to deliver CF content in distributed mode, but when we created the sites on the frontend server, all sites on that server began crashing. We uninstalled the frontend config, and the next day the application server began allowing only one web app to run; attempts to access any other web app produce an error similar to "The method getWebPath was not found in component resourceScheduler.components.dataFunctions." The component location changes to the most recently restarted app. This is on a Win2003 box; my first suspicion was an isolation issue, but I have even tried moving each site into its own app pool, with the same results. Ideas? We need to stabilize the app server so we can get back to work on configuring the frontend server; any help is greatly appreciated.
