To create a link between two SQL Servers you need to use the sp_addlinkedserver and sp_addlinkedsrvlogin stored procedures.
First,

sp_addlinkedserver @server='DBLINK01',@srvproduct='',@provider='SQLOLEDB',@datasrc='SQL-HOU-01';

Where,
@server is the name of the link
@srvproduct is the type of product, by default SQL Server
@datasrc is the server you link to
Then, you need to set the username and password to use on the link.

sp_addlinkedsrvlogin 'DBLINK01','false',null,'sa','Pa$$w0rd';

The first parameter is the name of the link to use,
The fourth is the account of the remote server to use,
The fifth is the password for the account.

I was having trouble adding configuring Database Mail on a SQL2005 server today.
I followed the wizard just like I had done on the previous 6 servers, but this one just didn’t want to add it. It was giving me an error about not being able to insert a NULL into the server name field, although I was giving it a server name.
I tried manually adding the data into the table, but of course that didn’t work. You have to use a stored procedure.
You need to use msdb.dbo.sysmail_add_account_sp with options like below,

msdb.dbo.sysmail_add_account_sp @account_name='company.com mail server',@email_address='john.doe@company.com',@display_name='John Doe',@replyto_address='john.doe@company.com',@mailserver_name='mail.company.com',@port=25;

DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
SET @path = 'C:Backup'
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN ('master','model','msdb','tempdb')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor

You can list all the databases on a SQL server by running the following query.

SQL> select name from sys.sysdatabases

SQL> sp_dropserver 'oldservername';
SQL> sp_addserver 'newservername';

don’t run in same batch.
the two statements must be executed separately.
via sp_addserver Transact-SQL.
