Unanswered: The timeout period elapsed prior to completion of the operation
I'm using two different server for application(.net version 1.1) and database(sqlserver200) with win2k3 environment. I'm getting the below error message all the times. I've veryfied the communication between the two server is fine.
"The timeout period elapsed prior to completion of the operation or the server is not responding"
Since the app is .net 1.1, I will assume you are using SqlClient apis.
If so, the application code has the timeout on the SqlCommand object set to low. You'll see this error if the app issues a query that doen't respond in time. I think the default timeout for SqlCommand is 60 sec. You need to set it higher.
