uisng Comcast DNS. The Event Viewer doesn't have any error related to the DNS. How do you troubleshoot it? A: From the description, I understand the issue is that nslookup failed with error "query refused" and your ISP DNS server shows as "An unknown error occurred while validating the server" in DNS forwarder list. If I misunderstand, please don’t hesitate to let me know. Do you have configured a primary or secondary zone in an error occurred while validating the available time for this resource your DNS server for comcast.net? If so, since you have already had DNS forwarder configured, you don't need to configure any zone for comcast.net, I suggest you delete it if any and test again. Also this issue could be caused by the incorrect DNS cache. I suggest you run the command below on this Windows 2008 server. Net stop netlogon net start netlogon ipconfig /flushdns ipconfig /registerdns After that, please test again. If the issue persists, please help me gather the following information: 1. Please help me gather the debug logging for DNS. a. In DNS console, right click the DNS server and go to Debug Logging tab. b. Select "Log packets for debugging" and select all the available options. c. Specify a log location. e. Reproduce the issue and gather the debug log, then disable the debug logging. 2. Please collect MPS report on the server (PFE version) for the analyzing. The MPS Reporting Tool is utilized to gather detailed information regarding a systems current configuration. The data collected will assist me with fault isolation. ===================== a.

Error Image :http://www.chicagotech.net/images/dnsissue4.jpg An unknown error occurred while validating the server. Need urgent h August 20th, 2015 11:42am Hi Hi_SGH, According to your description, when you add a DNS forwarder, unknown error occurs, but when you add the same IP address on other server, it works well. We may perform a network traffic capture on the server that has problem and on the server works well, compare the packets when you add a DNS forwarder. In general, when you add a forwarder, the server will query for the PTR record, then send SOA query to the remote server. If the remote server receives the packet, it will send back response-success packet. We may check if the server with problemcould receivethe response-success packet from the remote DNS server. Besides, the result of validation doesnt affect forward function, when DNS server forwards query to the remote DNS server, it refer to the IP address of the remote server.
