I took over a business network where the previous IT guy named the local network domain (sample.com) with the same name as the website domain name (sample.com) for the business, which caused internal DNS problems. We could not get to the external website. I was able to solve it in my Win2003 server environment by adding an A record with the name "www" to the internal DNS server that pointed to the external IP of the web hosting company.
Recently, we migrated to a new DNS server (Win2008 R2) and have not been able to see our own website internally since the migration. I have tried deleting/purging the A record and recreating the A record. We are using forwarders that point to opendns DNS servers. When I type in my internet browser www.sample.com
, I keep getting the IIS homepage screen for the internal server.
I have recently reviewed articles referencing EDNS and DNS issues but not 100% this is my problem. Article here> http://weblogs.asp.net/owscott/windows-server-2008-r2-dns-issues
Does anyone have any ideas on how to resolve this issue in Win2008R2 DNS environment?
