We have SBS2011. If we set the internal NIC to point to itself the server cannot get out to the internet. Can only get out to the internet if we set it to google DNS or something like that. Also, we have issues with clients getting out to the internet using the internal DNS server. Doing some nslookup stuff made it seem like the server IP was being blocked, so we changed the IP on the server and it worked for a bit, but now the same things are happening. Also we can't add machines to the domain as it can't find the .local domain name by pinging. Wondering if we need to reinstall DNS on this box. Suggestions first?
