We have a hub spoke network (not fully routed) where the spoke sites cannot connect to each other. When users from 1 spoke office travel to another they cannot open their Excel offline files without waiting for 5 minutes per file (sometimes it doesn't open at all) If the users unplug their cable it works instantly(both before it tries to open the file and while). When the users from the spoke offices plug into the central office they are able to work, it seems to connect to their remote sites detect its slow network and then opens locally. This is causing us a nightmare so any advice would be really appreciated. Many Thanks Darren
