I've got a database file connected to my server using the walkthrough at,

http://msdn2.microsoft.com/en-us/library/ms165673.aspx

I've got my Visual Basic application connecting to this server and database using the connection string,

"Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;Database=imei2;Data Source=mycomputer\sqlexpress"

Where IMEI2 is the name of the database, and MYCOMPUTER is the name of my computer.

--------

The strange thing is, if I build my application and run it from my local harddrive it works fine. I can also copy the files to my other harddrive and it runs fine there also ..

BUT, if I copy it to a network drive it crashes when loading the database.

Also, if I try to run this from other computers (where .NET sp1 is installed) it also crashes !!

Why this ??
How can this happen ??
I can't find any logical solution to this probelm ??
