Windows 7 No Internet Access On 2003 Domain - Can't Ping Default Gateway
Posted on 2010-09-14
Fresh build of Windows 7 Ultimate. Imaged the system at my home (standard cable connection), downloaded and applied all updates, joined to the company's domain via VPN, maped printers, drives, etc. Everything worked flawlessly until I got the system to the office.
While in the office the new Windows 7 system can access network resources (file shares, printers, browse computers, etc.) but cannot access the internet. The network notification area states "no internet access".
Server is 2003 standard. Approximately 10 other systems (all XP) with no issues.
- Have tried both DHCP (provided by the domain controller) and static addressing. While on DHCP the system pulls all configurations fine. Even enabled a separate DHCP scope on the router and pulled from there with the same result.
- I am getting DNS resolution. Internet addresses are resolved correctly, but obviously pings to anything external are not successful. DNS is provided by the domain controller.
- Interestingly, I can NOT ping my default gateway (router). When I attempt to ping my default gateway (which I confirmed is correct) I get: reply from 192.168.1.111: Destination host unreachable. Note that that IP (.111) is the Windows 7 system's own IP address. I can ping other systems on the subnet.
- Updated the NIC driver from the standard Microsoft to the latest from the vendor (though NIC driver seems unlikely as the system worked perfectly from my house?).
- Windows identifies the connection as "domain". Checked the security settings for the domain type and toggled all settings on and off but no difference.
- Disabled the Windows firewall, but same result.
- Disabled IPV6
- Disabled and enabled the network adapter
- Tried an automated repair of the connection and got the result "default gateway is unavailable" - only suggestion was to ensure the gateway is on the same subnet (of course it is).
- Brand new build so no other software installed to disable or uninstall.
- Cleared DNS cache
- Tried a different port and cable for the heck of it
- No pending updates on the Windows 7 system or the 2003 server
- When originally configuring the system from my home, while connected to the VPN and joined to the domain everything worked fine.
Also, the only other Windows 7 system (Home Premuim in this case) ever used in the office could not access the internet from the office either. I ran through a small subset of the troubleshooting above on that system (got a DHCP address, name resolution fine, etc.), but didn't get enough time to get into detail on that system. That system was NOT joined to the domain.
Any thoughts? At this point it almost seems like a router issue to me? It's just a cheapo small/home office router (don't remember the make/model right now).
