A compliant HTML document is a compliant HTML document regardless of
where it is published.

It doesn't. Unless you have a validator installed on the Intranet e.g.
if you are be validating your pages as part of the publication process.

Why would the browser be trying to connect to a web site if there is no
Internet access? What are your users doing that will cause the browser
to try and fetch the DTD?
>Does the validation "fail"?
What validation? Browsers do not validate HTML documents.

No, if you have a validator on your internal systems then it should
have commonly used PUBLIC DTDs such as HTML 4.01 stored in its local
catalogue.

Do you want your pages to be compliant with the specs or not?
Perhaps more importantly do you want to trigger the Quirks or Standards
Compliant rendering mode? That's all that web browsers use the doctype
declaration for.
