Hi,

we have a problem on some systems working with winnt4 sp6, mdac 2.5, access 2000 mdb, jet engine 4.0.
 
If our (vb6-)programm wants to save a date in the accass-database (datatype in db is date and in the programm it is also date) and it is a date between the first and the 12th of a month, the format is us-englisch instead of german (german format: dd.mm.yyyy; for example the 12th of january is 12.01.2004 in german, in the database it changes to 01-12-2004). If it is a date after the 12th, the format is saved in german (for example the 13th of january will be safed right as 13.01.2004).
This problem comes on some pc, which are used with various software and not on a clean winnt4 installation. It semed to be that there are one or a few dll changed.

Which are they? What else could be the reason for changing the format of the date?
