Hi Friends,
In an network environment, PC is configured as " automatically detect settings" on Internet explorer, it will query for the proxy server using WPAD (Web Proxy Auto discovery Protocol). it can be achieve two ways DHCP / DNS server.
Use the dnscmd command-line tool to manage the global query block list. Open a command line prompt, and then do the following:

here problem we faced in DNS server,
Application team has migrated to New DNS server 2012. From PC , we are unable to ping wpad.domin.name but it exist in the DNS server.after all the troubleshooting, we found above Microsoft 2008, global query block list is enabled . hence, WPAD will have local IP address will not be resolve untill it is unblocked.Use the dnscmd command-line tool to manage the global query block list. Open a command line prompt, and then do the following:
-
To check whether the global query block is enabled, type the following:
dnscmd /info /enableglobalqueryblocklist
-
To display the host names in the current block list, type the following:
dnscmd /info /globalqueryblocklist
-
To disable the block list and ensure that the DNS Server
service does not ignore queries for names in the block list, type the
following:
dnscmd /config /enableglobalqueryblocklist 0
-
To enable the block list and ensure that the DNS Server
service ignores queries for names in the block list, type the following:
dnscmd /config /enableglobalqueryblocklist 0
