I have a Windows 2003 network behind a firewall. My website is hosted by my ISP. I have a CNAME record with my ISP that resolves http://xyz.com to http://www.xyz.com. However, I cannot do this internally on my network. There, http://www.xyz.com points to my external website; however, http://xyz.com does not resolve and nslookup tells me that it is resolving to my DNS server. How can I fix this and will it break my internal DNS capability?
