Internal/public domain names and DNS

Hi Experts,

I'm trying to decide on an internal domain name for our office network. We currently have a public name, we'll call it "abc.com", registered and pointing to our externally hosted web server. Originally I was planning on just using "corp.abc.com" as the internal network name but after reading more about DNS it seems like this could create problems down the road if we ever wanted to host anything from our office network (like exchange). I'm new to DNS but it seems like names with a master name abc.com would eventually try and hit the web server to resolve names and we'd have to route name resolution from the web server back to the internal office DNS. The long hops might slow things down. I’m thinking of either using an entirely different domain or something like "abc.local".

From your experience, which would you recommend? What are the limitations and advantages of each method? Is having a name like "corp.abc.com" really even a problem or am I way off base?

Any further light on this issue would be great.

Thanks Experts,
