I'm having an issue where an application (MS Nav 2015) invoked query (Select) on occasion is receiving a login timeout. This issue happen sporadically, and the query itself is run at 15 minute intervals throughout the day without issue. The remote login timeout was set at 10 seconds, which I have reconfigured to 35 seconds. However, I'm curious as to why login timeouts occur in completely random intervals. Error Message : DS-Log-Live, D-Plan All Day Automated JAS response processing., A call to ADODB.ConnectionClass.Execute failed with this message: OLE DB provider "SQLNCLI11" for linked server "S-FEN-SQLHYP-03" returned message "Login timeout expired".
