You need to google on 'SMO run SQL Script .NET'

(I hate the black background of the blog)

I posted a solution a while ago here in response to Michel Fournier, but I don't remember in which forum and quick search didn't find it.

>>>If I understand correctly, why not just generate change scripts for whatever is different on the server and put them in a folder. When the laptops come in and hookup, the go to that folder and run the change scripts. Give each script a guid as a name and let the laptops maintain a list of guids for scripts they have run, only running those that haven't been run before. Probably need to figure out sequencing but that shouldn't be too difficult, especially if you assign the guids as newsequentialguids ( or just some other id system )
