Error :

[SQL Native Client]Named Pipes Provider: Could not open a connection

to SQL Server [2].

[SQL Native Client]Login timeout expired

[SQL Native Client]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.

1. Already opened DBEngine Remote Service with "Using both TCP/IP and named pipes"

2. Add in "C:\windows\system32\drivers\etc\hosts" of the other server (it use to connect to DISERVE-DB-01.) as below

192.168.1.21 DISERVE-DB-01

How can i do next????? Many thanks for your advice.
