Windows Server Networking

[Judahnator]

I have a Windows Server 2008R2 installation inside a ProxMox virtual host. It is able to access local network resources, but no internet resources.

Other machines on the same virtual host work just fine, so im thinking its a problem with windows.

 

It worked just fine for months, but last night i started getting calls from clients who use my email server. They said they got messages saying that messages they were sending couldnt be delivered because the server couldnt find the recipiants domain.

 

I ran a traceroute on a linux box (same host and network adapter):

traceroute to 4.2.2.2 (4.2.2.2), 30 hops max, 60 byte packets 1  192.168.0.1 (192.168.0.1)  0.644 ms  1.004 ms  1.336 ms 2  CPE-75-87-248-1.natsoe.res.rr.com (75.87.248.1)  25.448 ms  26.252 ms  26.332 ms 3  tge7-1.mscwidbw01h.natnow.rr.com (65.28.215.17)  18.899 ms  19.714 ms  19.651 ms 4  tge2-1.plmnwaen01r.natnow.rr.com (72.129.43.40)  19.789 ms  19.689 ms  23.171 ms 5  tge0-4-0-0.sttlwawb01r.natnow.rr.com (72.129.43.100)  40.167 ms  40.994 ms  40.899 ms 6  107.14.19.112 (107.14.19.112)  35.769 ms  33.571 ms  33.526 ms 7  ae-0-0.pr0.sea20.tbone.rr.com (66.109.6.145)  30.535 ms  27.107 ms  28.148 ms 8  te-4-3.car4.Seattle1.Level3.net (4.71.156.109)  77.580 ms  78.454 ms  78.438 ms 9  ae-2-70.edge1.SanJose1.Level3.net (4.69.152.78)  51.166 ms  52.949 ms *10  b.resolvers.Level3.net (4.2.2.2)  72.898 ms  56.133 ms *

here is the traceroute for windows:

 

Windows says it can connect to the internet, and there are no problems. Diagnostics say it can connect just fine, but errors out when trying to do windows update or get new help content.

 

Does anyone have any ideas on why this would suddenly stop working?

 

Thanks,
