Hello. I have a strange issue.
My 2003 windows server is the main DC. Suddenly after no changes at all on the server, websites won't load most of the time, and the few times they do load, they are extremely slow.
We have a T1 at the site and it is working just fine as far as I can tell. I can upload and download data at full speed to my test sftp server.
So internet speed is fast, but most websites come up as can't be found. It seems like a dns issue to me. However I can ping websites and it shows their ip address quickly. Pings usually say unreachable though.
What could my issue be? I have tried changing the dns servers manually to Google's servers 8.8.8.8 and 8.8.4.4 just to test dns and it is still slow.
-Thanks
