You need to create a Linked Server on Server A to Server B.
Its under Security in EM (Enterprise Manager).
Or if you want the T-SQL way:
EXEC sp_addlinkedserver SERVER_B, N'SQL Server'
EXEC sp_configure 'remote access', 1
RECONFIGURE
GO
exec sp_serveroption @server='SERVER_B', @optname='data access', @optvalue='TRUE'
go
Then you can query as follows:
select * from SERVER_B.DATABASE.OWNER.TABLE
Keep in mind you have to be an SA to set this up.
Let me know if it works out.
