Hi! I've just re-install one of my file server(domain controller) running win2k svr standard edn and restored back the shared folder. I've also run dcpromo and install the dns and dhcp component. The server is using integrated AD. The problem i encountered now is that, whenever i map to that shared drive using the server name. The network drive will be disconnected by itself after 1-2 days. I will need to disconnect it and restart the pc in order to map back that drive. It work fine if i map using the ip of that server instead of the server name. Any idea what's wrong here? (In our network, there are 2 DC) Thanks.
