Any idea what is the cause and how to solve this issue?
By the way I am using a linked Server

SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].
OLE DB provider "SQLNCLI" for linked server "VCDB" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "VCDB" 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.".


Thanks
