Timeout expired... Error detected by Database DLL
 

I m working on a VB project with MS SQL SERVER 2000 as backend database and Crystal Report 8 for Reports.
The problem is :

When showing a report, after some moments error comes as

Microsoft OLE DB Provider for ODBC Drivers:
[Microsoft][ODBC SQL Server Driver]Timeout expired

When I click on OK Button, again a message appears

Error detected by Database DLL

But when I Reinstall the setup of the project, it (exe of the project) works well and shows the report for one time.
But next time it again shows the same aforesaid error.

Plz Help.

That might be cecause of the resource is busy and it is taking too long to establish the connection with database.
