Hi, I have a stange problem with Server 2008 R2. Configuration is: Server with 2 LAN card with Hyper-V there are two Windows 2008 R2 SP1 running The main 2008 use one LAN card and it's IP is 192.168.0.x (intranet) ->gateway 192.168.0.250 the virtual 2008 use the second LAN card and it's IP is 172.16.1.x (internet) -> gateway 172.16.1.250 All IP are static The problem is that the main server stop to navigate internet. I don't know why but, if from main server I try to do a tracereroute I look this: C:\Users\Administrator>tracert 8.8.8.8 Tracing route to google-public-dns-a.google.com [8.8.8.8] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms 172.16.1.250 2 ^C C:\Users\Administrator> It try to use the gateway of the 2° LAN card. How I can force the main server to use the correct gateway?
