How to determine if MY DNS server is responding?
I have a single DNS server for internal use. Two more, OPENDNS servers,
complete the list of three DNS servers given out via DHCP. Certain web servers are inside our network with one private address, and outside in the big bad world on a different public address. I would expect that any internal request for DNS should go to our internal DNS server, (it is at the top of the list, first in line,) and return out internal address. This is a good thing since we can not access the external address from inside our network. However, it does not appear to be working consistently. For some people, sometimes, they can not get to the webservers, and pinging the address returns the outside address. How can I tell what DNS server is giving the results that a system is using? Not supposed to be, but actually? Any ideas why some systems some times would not be getting the proper replies? The DNS server is a win2003 server. Phil |
