I have made an application on my own computer, and at the time of creation there were no problems at all.
I runned this connection string on my local computer, and it worked perfectly.
private SqlConnection connection = new SqlConnection("Data Source=LT004512\\SQLEXPRESS;Initial Catalog=databasename;Integrated Security=SSPI;");
However, when i edited the connection string to the following (becouse it had to run on an other computer), my program didn't start.
private SqlConnection connection = new SqlConnection("Data Source=VG-VJGZTEST\\SQLEXPRESS;Initial Catalog=databasename;Integrated Security=SSPI;");
No big deal i thought at first, but it also didn't work at the cliënt server.
For some reason, it only worked at the local host, and it looks like it can't get a connection.
Does anyone know what steps i have to take to counter this problem.
