problem with my published application

hello!

i have published my application, that worked fine.

i am running it over a network, so the database is on the server and the folder shared as the z:/ drive.

my application will read from the database but not insert into it!

if i run the application on my laptop and tell it to read/write to the database on the c:/ drive it works fine so there is no problem with my sql or anything!

i have set the user permissions on the server to full so they can read/write to the database.

does anyone know what is going on and could help me out!!!

thanks alot,

Iain
