issues? No. Limitations? Sure. Many of the enhancements introduced in later windows versions for active directory require the functional levels be raised. You wont be able to do that with 2003 DCs in place.

So you'll get and keep existing functionality, but wont necessarily be able to take advantage of new features.

Presumably your current domain and forest functional level is windows 2003.
