Hi guys
I had some trouble with my Setup as i took over from someone else. I had some trouble setting up the VPN server on the windows server 2008 R2 and by the way the issue was the internet was getting too slow until it was literally stops (ping time 10000 ms ) if we have changed the modem the problem would temporarily resolved but it comes back after a couple of weeks or days. i play around with the DNS server and problem is still there when i point the DNS to the Telstra DNS servers.
this problem has caused another problem which is my question , it came to me when i tried to add another PC to the Domain and it could not resolve the AD to connect the domain. plus the existing computers are not resolving the password update and so on which seems to be from the same problem any idea about this issue or anybody had some similar issue and resolution i will highly appreciate it
