The ISP DNS addresses should be in DNS Properties|Forwarders tab instead of in NIC network properties page Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Hi Tcmuhammed, There are two errors in your dcdiag log. 1.Please make sure default gateway 192.168.0.1 is connected correctly. Default gateway test . . . : Failed No gateway reachable for this adapter. 2.Please remove these two DNS entries and add them into the DNS server like Dave suggested, and test if “nslookup www.Microsoft.com.” could properly resolve in your DC, XP, Win7 client. [WARNING] The DNS entries for this DC cannot be verified right now on DNS server 212.77.192.60, ERROR_TIMEOUT. [WARNING] The DNS entries for this DC cannot be verified right now on DNS server 212.77.192.59, ERROR_TIMEOUT. 3. You can “repair” the connection to recover the internet connection. Please execute “repair” details command to find which one could resolve the issue. http://support.microsoft.com/kb/289256 4. Your DC/DHCP/DNS server in one server, right? Please post “ipconfig/all” result from one XP client and one problem Win7 client. Regards, Rick Tan

Hi Thank u for replay, DHCP installed in router i am using Server 2003 Standard Edition i check the default gateway address, i got it's issue, the gateway address some time not connecting (we are
