Nulls vs Blanks

Until yesterday it was imposible to delete a field that did not allow nulls
in Enterprise manager (SQL2000) the InfoPath Clients connected to such table
s
saw red asterisks in all the required fields according to the information
provided by the SQL schema.
This has now changed on all instances and all servers without apparant
reason. now I can delete a field that does not allow nulls and it is
registered as a blank. Infopath clients are not forced to include all
required fields prior to submitting.
What could have changed?
Thanks
IT PHYTOSANThis might be better off posted to an InfoPath newsgroup (like
microsoft.public.infopath).
