nslookup is a standard tool included with windwos that can be used by dns adminstrators for querying any dns server at the command line.
You can use it to directly query edgedirector servers to check that your records are correct and available before going live.
all of the following instructions presume a carriage return at the end of each line. To start nslookup in interactive mode, open a command prompt window and at the command prompt type: nslookup without any arguments. At this point, nslookup is in interactive mode and set to use your default dns servers. now, point nslookup at a particular dns server, for example ns.example.com, type: set server=ns.example.com. notice the trailing dot, nslookup requires them to avoid appending any default domain, this is required for all names, in all commands in nslookup if you would like nslookup to display full debug information, type the following commands: set debug set d1 set d2 this tells nslookup to include as much detail as possible nslookup defaults to querying for A records on startup. to change the type of record for a session to, for example MX records, type: set type=MX the record type can be changed at any time while you are at the interactive nslookup prompt
then issue the query by typing in the name you want looked up of currently set dns record type type: example.com. notice again, the trailing dot if an MX record exists for example.com, it will be displayed, and because you have full debug turned on, you will see a lot of additional information. you may want to leave debug mode turned off to begin with then, if you want to see the NS records, change the type by typing: set type=NS you can now issue queries for the NS records. hint: the up arrow can be used to recall commands from the command buffer when you want to quit, type "exit"
