Fresh install of Server 2008 Std.  Can pull IP, or set as static and ping router, dns, and google (and others), but cannot browse internet in IE.  Also, Network and Sharing center constantly changes from local only and local and internet.  Firewal disabled and IE SEC diabled.  Internet security in IE set to med-high.  Have two nics but disabled one for the time-being.  Also, disabled IPv6 binding.  Had internet once for about 30 secs.  No more as of then.

(i)Sounds more like a router issue or firewall issue.  Do you have anytype of network filtering?  First thing to check do nslookup cnn.com on a machine from a command prompt.  Then if you get a bunch of reponses, do a telenet to one of the ip addresses like this  TELNET xxx.xxx.xxx.xxx 80  

See if you get a blank screen or just a can't connect.. if you get anything other than can't connect then you are connecting and it's something else, if you get can't connect something is blocking you from getting to that website on port 80 and you probably need to look at filtering devices software other than that machine.. if the machine gets can't connect then you probably need to start looking at internet security software on the machine

(ii)are you using the internal dns server..? check the dns address of your internal dns and isp dns address settings

(iii)Sounds like a firewall might still be active and blocking you even though you believe it to be uninstalled or disabled.

Have you checked this machine for Virus, not just malware

(iv)Do you have any malicious programs set to run on startup?  Check by opening regedit, then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Do you have any programs that may be blocking you, like Norton Internet Security or some kind of firewall?  Are you connecting through a cable or a wireless access point?

(v)First, you need to determine if DNS is still working properly.  If you are experiencing a DNS issue, then you could still ping an IP address on the internet, but would not be able to resolve or ping a URL.

When you are unable to browse, goto a CMD prompt and type "ping www.google.com".  If you don't get replies, try "ping 198.6.1.5".  If you do get replies from that one but not the other, then it is a DNS issue.

If both ping fine, you can reset the IP stack very simply with this command:
"netsh int ip reset c:/netsh.log"
Then reboot and see if the problem persists.

I have tried alternate browsers.  No luck.  FIrewall is definately off.  DNS, DHCP, internet is all handeled by Cisco Router.  I can ping everything, but no access from apps.  Can't windows update, can't activate, can't update antivirus or register it.  But pinging works fine...

(i)Is the preferred DNS server specified in TCP/IP properties working at another client? Pleasae post the output of ipconfig /all from this computer and from a computer that can browse internet.
      Also make sure that proxy setting of the computer is sae with the client that works (no proxy should be defined in most cases, in internet explorer settings>connection)
     You dont need 3rd party tools for name queries. You can use nslookup. Just type nslookup in cmd then type the web.
    Also running the following tool may work http://www.snapfiles.com/get/winsockxpfix.html

You'll have to give me some time.  I decided to just reload it.  Remember, it was a fresh install.  so there was no reason for it not to work.  all the other pcs on the network are configured dynamic and work fine.

Also run pathping www.google.com and see where the packets drop.

It might be worth mentioning, that it drops between "local only" and "local and internet" status every other minute or so...  more so on bootup, and less often after being on for a few minutes.

Tried step (i).  No luck using IP address.

Ip setting in this order:  ip address, subnet, gateway, dhcp, dns1, dns2

Server:  192.168.1.63, 255.255.255.0, 192.168.1.254, 192.168.1.254, 65.32.1.65, 65.32.1.70

Working client:  192.168.1.27, 255.255.255.0, 192.168.1.254, 192.168.1.254, 65.32.1.65, 65.32.1.70

treid a tracert on www.google.com, there was a request time out after the gateway, but it traces all the way to google with no problems after that...
