Database Logon Failed on drill down

Printed From: Crystal Reports Book — Forum Name: Talk with the Author

The report shows up fine but when i drill down immediately it works fine. If I drill down after sometime it gives the error Database Logon Failed.

Please respond to it as it so urgent.
 
 
 

I am using visual studio 2005,sql 2000 and crystal reports 11.5

Sorry, but I have no idea. Is it possible that it is timing out and losing its connection to the database?
