I have two domain controler (replicate) them and are DNS on Windows 2008 R2
In fact on opening a web page html we encounter a big problem with DNS.
it joined the snappshot Wireshark shows the multiple DNS requests to open a web page.
must be 3 to 4 DNS requests and about 30 seconds before the pc has an answer.
This problem of DNS is present only when one makes use of www pages, but I do not have the same problem on the Intranet that they are hard in our DNS.
please help me because the internet is becoming very slow
thank you very much
