The format YYYY-MM-DD is not a safe format, but its interpretion is
up to dateformat and language settings. The default language (and thereby
the date format) is set on login level, and may be inherited from the
server. I would assume that on W2K you had installed SQL Server with
us_english as the default language, but on Win2003, you have an installation
with a language which uses a DMY format, under which YYYY-MM-DD works.
