Hi All, <BR><BR> One Information system is available in my office. That is shared by all the departments. In one deparment the system hard disk is failed. So they changed the system. <BR><BR> So I have copied the Information systems exe in to the new system and try to execute. But it showing the error as connection couldn't be established. The information system is in Vb and Sql server. <BR><BR> If I am executing it in the server which is having the database or in the some other client no problem. It is working perpectly. <BR><BR> And I stop the running of the sql server and I tried, the same error is coming even if I am running it in the Server where the database is available as well as from any other client. So I can say it confirmly this is the sql server connection problem. what I have to do to share the database from a new client? <BR><BR> Thanks <BR><BR>Ezhil.
