I have a main store that has 5 branches which are connected using frame-relay. Each has a cisco 1750 router with their own subnet. Everything is running great but there is one question. There is a server at the main store and the pc's from the other branches (subnets) connect to this server over the frame using map network drive in win98. If this mapping (say drive G) on the branch side sits idle for some length of time - the next time that they go and try to use a program that requires drive G an error comes up and says unavailable. We do not have keepalive set on any router. Do we need to set keepalive? Would this solve the problem? Thanks in advance.
