Hello,please describe more details about roles/application running on the server. Also an unedited ipconfig /all so we can exclude DNS as a problem,that sounds for me is existing.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.

The ipconfig /all result is as below: C:\>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : delta-gpl Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Broadcast IP Routing Enabled. . . . . . . . : Yes WINS Proxy Enabled. . . . . . . . : Yes Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : HP NC7761 Gigabit Server Adapter Physical Address. . . . . . . . . : 00-11-85-51-50-D3 DHCP Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.1.3 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 202.188.1.5 202.188.0.133 There is no other third party firewall running on it.

Hello,remove the public DNS servers, 202.188.0.133 and 202.188.1.5from the NIC and use only domain internal DNS servers instead. On the domainDNS server configure FORWARDERS under the DNS server properties in the DNS management console and add there the external DNS servers.So the ipconfig should look like:IP Address. . . . . . . . . . . . : 192.168.1.3Subnet Mask . . . . . . . . . . . : 255.255.255.0Default Gateway . . . . . . . . . : 192.168.1.1DNS Servers . . . . . . . . . . . : 192.168.1.x (where x is your domain DNS server ip address)Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.
