Hi guys, I have a very strang issue. After 3 month using Win 7 RC 7100 my internet connection is not working. I tried to disable bonjur service and even uninstalled office 2007 and adobe reader. I don't know what else can I do. My internet connection on other Laptops is working fine.

I tried to set up manualy the IP4 configuration and it worked. So my DHCP service is probably is not working correclty. I tried to disable and enable. No luck

Hi,I would like to confirm the following questions first:1. Is this Windows 7 machine in a domain or a workgroup? Is it connected via wireless or wired cabled to a router?2. Does other machine connect to Internet normally via DHCP service?At this stage, it's highly recommended to upgrade the router firmware and reload its settings. If the issue persists, you can also temporarily turn off firewall on the machine and router (if it has).Thanks,Novak

Hi Novak, 1. Win 7 is in workgroup and I'm wired to router 2. Other machine are connected via DHCP with out a problem. I don't think it's problem with router. I have tried to connect in diffrent places with the same result. When I config. manualy the IP4 it conect to network so I see divices and computers but I don't have internet connection. I can open websites with ip adress but not with domain.

Is there another Windows 7 machine in the network? Can it work fine? Please also perform the followign steps for a test. 1. Modify relevant registry key via the following article: Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers 2. Refresh a new IP address a. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue. b. In the popup window, type the following commands and press Enter one by one: ipconfig /release ipconfig /renew Then, the new IP address will be obtained. 3. Upgrade the latest NIC driver for Windows 7 Thanks, Novak
