hi everyone, I am challenging a problem in a network with windows seven, I have wireless wifi area in which I am provideing wireless internet. my DHCP server and Router is a win2k3 based system, which works fine for all clients, such as win xp, windows mobile, and every hand held I have tried there. But my problem is with windows seven clients. some of them doesn`t get IP from DHCP server. and some get but cant ping the default gateway, it says destination host unreachable. I have tried setting manual IP address on these clients but it doesn`t work and I get the same error. I even replaced my WIN 2K3 with a linksys WRT to perform NAT and DHCP server, but I got the same results again. I can not force my customers to change their windows from seven to any thing else. this issue is putting me in a bad situation in my job, please help me.

Hi, Thanks for the post! According to your description, you DHCP cannot successfully assign the IP address for your Windows 7 clients. Even using valid IP, the clients still get the “destination host unreachable” error message. Try to turn off the firewall to check if the issue persists. Run cmd as administrator, input: ipconfig /flushdns ipconfig /regsterdns ipconfig /renew If it doesn’t works, please provide us with the result of “ipconfig /all” Meanwhile, please also ask this question in Windows Server Forum.
