I am facing this problem for the first time.
Details of the Computers/Network
192.168.1.1 – Internet Router
192.168.1.250 – Wireless Router
192.168.1.253 – Canon Printer
192.168.1.254 – Windows 2008 R2 Server Standard Edition
192.168.1.5 to 192.168.1.225 – Available for client computers
Client Computers range from Windows 8 to Windows XP.
The server has been configured as the Primary Domain Controller with DNS, IIS & File Server. DHCP has also been configured on the server however using Open DHCP Server (open source DHCP Server) which shall allocate necessary IP address to the clients. The IP are leased for 12 hours.
The whole network crashes without any proper reason at random. All the client and the server are not able to ping with each other. When we try ping, we get the message Destination host unreachable on all clients and server (pinging to the internet router, printer and wifi router (which are not part of the domain) gives the same error). But if I restart the server and the network, the everything begins functioning properly. There is no error message in the event viewer of the server also in this regard.
Pl advise what could be the reason behind this issue and how to solve the same.
Thanks and regards,
