i am executing the daily scripts

and the main thing is that if i run the scripts after 5 minutes it works.

But the next day i am getting the same error again and some times the error doesn't come and everthing works smoothly

OLE DB provider "SQLNCLI" for linked server "ServerTest" returned message "Login timeout expired".

OLE DB provider "SQLNCLI" for linked server "ServerTest" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
