New Computer on Domain cannot connect to Internet

Discussion in 'Server Networking' started by Frustrated by Outlook, May 1, 2007.

  1. Hi All,
    I have just started the administration for a new company and have took over
    the old regime's system.
    I have replaced an old 98 computer with a new XP one. I have connected this
    to the domain (Server 2003 local domain) just fine and everything works
    except internet connection. They do not use any proxy's or anything so am
    stumped as to why this one PC will not connect and all the others on site
    All settings appear to be the same as the others.
    Any ideas?

  2. AD clients that are Win 2k or XP rely on DNS to find the domain. That DNS
    server should also provide Internet resolution either through forwarding or
    root hints.

    What server does the XP computer use for DNS?

  3. This company just have the one server supplying their needs. The DNS settings
    if I remember correctly were the same as the other clients however I could be

  4. No the machine is not able to access any website through the IP address. All
    machines show the same DNS server. And there are no static IP's or any other
    settings set. The machine gets all this through dhcp.
    The one thing which it may be down to, and please advise if this is correct.
    But I am not able to get any further than the default gateway. The gateway
    appears to be a firewall they have in place. So my guessing is that the mac
    addresses of the PC's allowed to access the internet are able to do so and
    this new one is not.
    Any ideas??

  5. Check the firewall setting (On/Off) ofn the XP system.

  6. Did not work with the Firewall off or on.

  7. Actually taking a 2nd look, I am now unable to access the firewall controls.
    Whether logged on as a user or administrator I am unable to turn off the
    Firewall. Any ideas?!

  8. Yes, you should be an administrator

  9. As said in my previous post, I had tried as both administrator and user.
    Neither gave me the option to turn it off. The box was greyed out.
    Any ideas?

  10. Run these command and Check the reply

    Netsh firewall show state
    Netsh firewall show config

    Additionaly, I assume you don't have anti-virus software installed , and if
    you have then disable it to check if it's culprit.

  11. Additionaly, If you have Group Policies defined then check this :

    Click Start, Run and type Gpedit.msc
    Navigate to the following branch:
    Computer Configuration
    => Administrative Templates
    ==> Network
    ===> Network Connections
    ====> Windows Firewall
    =====> Standard Profile

    Set the following options to Not Configured (defaults)
    Windows Firewall: Protect all network connections
    Windows Firewall: Do not allow exceptions
    Windows Firewall: Define program exceptions
    Windows Firewall: Allow local program exceptions
    Windows Firewall: Allow remote administration exception
    Windows Firewall: Allow file and printer sharing exception
    Windows Firewall: Allow ICMP exceptions
    Windows Firewall: Allow Remote Desktop exception
    Windows Firewall: Allow UPnP framework exception
    Windows Firewall: Prohibit notifications
    Windows Firewall: Allow logging
    Windows Firewall: Prohibit unicast response to multicast or broadcast
    Windows Firewall: Define port exceptions
    Windows Firewall: Allow local port exceptions
    Exit Group Policy editor.

    Is your firewall configuration being handled through Group Policy? If
    so, even the administrator will not be able to manually manage the firewall.

    Remember, Administrator accounts are not immune to Group Policy that is
    being thrown their way.

  13. What I am confused about though is that the Firewall was off to start with
    and is now on. But surely this would not stop internet access??
