we're having a problem of not being able to use any external dns like google's 8.8.8.8 as our dns server except our internal dns which works fine..
we have 2 dc , both dns servers (server 2008 r2)
when i change the dns setting statically on any on our clients to an external dns, it wont be able to resolve any names or open websites.but it works fine with our internal dnses. i want to figure out what could cause this issue? i checked configurations on our router and there was no settings restricting the dns
do you have any idea what could cause that?
