Trying To Create A View Across Two SQL Servers

I have two machines running SQL server. I need to create a view that contains data from both servers on Server 2.

ex:
Server 1 contains:
database (Employees)
Table (EmpMaster)
Column (EmpNumber)
column (EmpName)


Server 2 contains:
database (Training)
Table (TrainingEntry)
Column (EmpNumber)
Column (TrainingDate)
Column (TrainingDescription)

If the two tables were on the same server and in the same database, I'd just write the following:

select
TrainingEntry.EmpNumber
,Employee.EmployeeName
,TrainingEntry.TrainingDate
,TrainingEntry.TrainingDescription
from TrainingEntry
Left Outer Join Employee on TrainingEntry.EmpNumber =
Employee.EmpNumber

The question is how do I handle going between two databases, and more importantly, how do I handle linking between two servers?

All examples are appreciated.

Thanks
