I have a network of 8 PC's and 1 Server. I can remotely connect to the Server using RDP just fine. Once on the server, I use RDP locally to connect to the 8 client PC's. I also have one of those PC's setup as a DVR with camera's connected. During the day I can RDP to this machine using the IP or Hostname just fine. But at night, I lose the ability to connect to this machine. I can connect to the network and RDP to the other 7 PC's but not to the DVR. I can ping it and get a response but nothing on RDP. I checked the PC itself, the settings, the router, everything. I can't figure out why it dies on me in the evening, then the next day, works as if nothing happened, no reboots necessary. Any ideas ? I don't need another solution like VNC, Logmein, etc. I need to make RDP work. At the moment it is almost midnight, I can ping the PC but can't RDP to it, it just says the connection timed out when I try. However, I know that if I physically walk up to the machine it will perform normally and show me the camera feeds.
