There is no editable field showing to type the name of the DL.
It is for all kinds of addresses from any source and the same for a
newly created DL or an old, existing one.
Please describe in painstaking detail, then, what you see in the dialog that appears when you click File | New | Distribution List in Outlook 2003. So far, nothing you've described matches any known Outlook behavior.
Also please put enough informaton in your post so we can remember what the original question was.

Too late. Someone already fixed it by exporting and reimporting the
Contacts.

Interesting.
Implausible.
Exporting and importing breaks DL's for everyone else.
