\\server1 is when u share a folder, not linked server.

you create linked server using sp_addlinkedserver

and u refer to objects in your linked server using four part notation

select * from server2.db2.dbo.Mytable

to increase the timeout period, you can run

sp_configure 'remote login timeout', 30

go

reconfigure with override

go

here 30 secs will be timeout duration.

In the example u gave, Server1 is the linked server. From the server where u created the linked server, you can write queries as

select * from server1.db1.dbo.myTable

Exec sp_addlinkedserver

@server='SERVERNAME/ IP', --//Logical name given to the linked server.

@srvproduct='', --//optional . Just for description

@provider='SQLServer', --//OLEDB Provider name, check BOL for more providers

@datasrc='SERVERNAME', --//actual remote server name

@catalog='DBNAME', --//default database for this linked server

@provstr = 'DRIVER={SQL Server};SERVER=MyServer;UID=User name;WD=pwd'

GO

Exec sp_addlinkedsrvlogin

@useself='false', --//false means we are going to use remote login/password

--//true means use local login/password to connect to remote machine (If local login/password does not match on remote machine then will fail)

@rmtsrvname='LinkedServerName', --//Exising Linked server name

@localLogin='null'

@rmtuser='Login' , --//remote login

@rmtpassword='pwd' --/

--------------------------------------------------------------------------------------------

--//Enable/disable some options

Exec sp_serveroption 'DBName', 'data access', 'true' --Enables and disables a linked server for distributed query access

Exec sp_serveroption 'DBName', 'rpc', 'true' --//Enables RPC from the given server.

Exec sp_serveroption 'DBName', 'rpc out', 'true' --//Enables RPC to the given server (required to call SP using Linked Server).

Exec sp_serveroption 'DBName', 'collation compatible', 'true'
