First try Helen Borreie's method, this is a classic way, and asured to work.

If you are working on Linux, you can try
http://kfbsite.googlepages.com
http://sourceforge.net/projects/kfb
kfb->DDLs->Domains->Alter Domain->Add/Drop NOT NULL

It is only a click away to Add/Drop NOT NULL to/from a Domain, WITHOUT touching any data in your table--data is kept and un-changed, but Domain definition changed.
