No SQL Server 2005 will not support design changes from any version of
Access now (and probably in the future).
ADPs are being sidelined if you have not yet invested heavily in this
approach revert to using an MDB for the application.
If you have invested heavily then continue to develop using SQL Server 2000
and then deploy on SQL Server 2005 (at compatibility level 8) if there is
something that SQL Server 2005 gives you that SQL Server 2000 does not (the
only thing I am aware of is that SQL Server 2005 Express is less restricted
than SQL Server 2000 Desktop). If you are not using desktop or express then
there is NOTHING -significant- that SQL Server 2005 gives you that SQL
Server 2000 could not do, especially as Access 2003 cannot use anything that
is new in SQL Server 2005.
Access 2003 can only connect to an exist SQL Server 2005 database, all
design should be completed using SQLS tools.
I suggest you check out the newsgroup m.p.a.adp.sqlserver and in particular
the posts of Mary Chipman of Microsoft on this matter.
