I have a server 2008 R2 Domain controller , file server.
It has lost internet connection.
It can ping the other servers on the network but cannot ping the router.
Host unreachable.
All network connections are fine.

    What happens if you do a tracert?? And did anything change in the router configuration? Is your entire network (and the router) on the same subnet??

    I have seen this on Windows 2008 servers

    Does your router have a limit of the number of internet connections allowed?

    Try clearing arp cache on router and on server

    Accepted Solution

    I found the problem.
    I reset the switch to which the router and server are attached, and all came back to normal.
