    Exclamation Win 2008R2 - Lost access to Internet (LAN is OK)


    Hello all,

    I have a problem, that appeared just recently, I need help with it please..

    Windows 2008R2 (x64) server doesn't have access to Internet, but LAN connections are fine, all PC's have access to server via LAN.
    AD, DNS, DHCP, IIS, WDS and WSUS running on server.

    NIC settings are the same as they were when I didn't have this problem, and everything worked just fine.

    I've tried following various Event ID's and their recommended fixes, but it didn't help.

    Can anyone recommend anything please? I'm all out of ideas and have been trying to fix this for weeks.
    I attached all event id errors below..

    Appreciate your comments!

    This almost seems like a DNS issue; I say almost because I think we need more information.

    Can you check to see if there are any errors under your DNS logs. Also, please post an ipconfig /all of your server. Can you ping a computer by both the IP address and hostname on the LAN?

    What happens if you ping google.com (wait for the actual error response). What happens if you ping google by one of it's public IPs (74.125.225.20)?

    Just to clarify, you mentioned Windows 2008R2 doesn't have access to internet but it has access to LAN as well as all other computers. Do all other computers have access to internet, or is everything down as far as the internet goes?

    Thanks for the replies.
    It seems like a DNS issue to me as well, just can't find the problem.
    Yes, all 10 other PC's on the same network do have access to Internet.

    Try changing your DNS server entries to point to the IP address of the server itself. Technically 127.0.0.1 should do the same thing, but if you haven't selected it to listen for DNS queries it may not work. Using Google's free DNS server (8.8.8.8) as a DNS server will cause issues with Active Directory. You should set that IP as a forwarder in your DNS server settings. So in short, set the DNS server entries in your static IP of the server to point to the server itself. Run an ipconfig /flushdns and see if that resolves it.

    I tried this before, and just now again, but it doesn't help.
    When I use this setup, I see a warning in DNS events:

    Event ID: 4013 Source: DNS-Server-Service

    The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

    Load your DNS snap-in. On the server name right click and select properties. Is your server set to listen for DNS requests on the appropriate IP(s)? Also if you select forward and reverse lookup zones. Under your domain, if you right click and select properties, is your server listed as an authoritative name server? I know it sounds silly, but for giggles if the above looks fine, you may want to just restart the server and see if that doesn't fix it. The only reason I say this is because that's actually what MS recommends as part of the troubleshoot process for that error; reference

    Server is set to listen to "All IP Addresses", and in the ip list, it does also list the server's IP
    "authoritative name server" - do you mean in the Start of Authority tab? yes, the server name is listed in the Primary Server field, like so: rufsrv1.rufil.local.

    Check the actual name servers tab; though I suspect it's in there. Did you restart the server yet?

    Yep, check both forward and reverse zones, name server tab has the server name. And I tried rebooting server just now. Still no Internet.

    anything else I could check?

    Can you ping the gateway by chance? I'm really at a loss at the moment. No one messed with NAT did they?

    In short, you're running into two issues. First, you can't resolve DNS. However, you can't resolve DNS because you can't get to the internet to forward any DNS queries. We know you can't get to the internet because you can't even ping Google by it's IP address (which does not rely on DNS at all). Your route to the internet looks fine. Has anything at all changed on the network or been added? Has anyone manipulated the server at all?

    Out of curiosity, can you run an ipconfig /all on one of the local machines that works for us?

    Yes, I can ping the gateway just fine.. no errors. And I haven't made any changes to the network after I setup the domain and got everyone joined (everyone has been using it fine for several weeks since then, and server had access to internet)

    here's an ipconfig /all from one of the machines on network, which does have access to internet:

    Under the DHCP snap-in what are the DNS IP addresses it's sending out? I noticed the server and workstation both have DNS addresses of 127.0.0.1, the server itself, and then Google's free IP of 8.8.8.8. Are you sure you don't have a router/firewall in the mix that's running DHCP as well; that's issuing out IPs and DNS entries as well? Usually all of the computers (including the server) would have a DNS setting of the local IP of the DNS server. You shouldn't need any public IP DNS entries because the DNS server will forward requests to a public IP for you; if it needs to.
