Compare of 2 tables with multiple output rows???

Question

I have two table which hold port and process information from a network scan.  One table is a baseline and the other is a recent scan.  The tables contain the ports and services from all the systems scanned for each system.  
I need to compare the two tables and show what the difference is.  One report showing just the unique ports not in the baseline and another to show a complete list of all the ports not in the baseline and the associated computer name.  I need both
the reports to be able to show if the difference is a port that was in the baseline that is not in the new scan or is a new port not in the baseline.
Here are the table formats I have:
Baseline
Date
Plant
ComputerName
Protocol
LocalAddress
LocalPort
RemoteAddress
RemotePort
State
ProcessName
Scan
Date
Plant
ComputerName
Protocol
LocalAddress
LocalPort
RemoteAddress
RemotePort
State
ProcessName

Answer 1

tablediff:- Just find the tablediff.exe and change the sourceserver,source database  -sourcetable and same thing you need to do it for destination.
Interchange it for the second run
C:\Program Files\Microsoft SQL Server\100\COM>tablediff.exe -SourceServer hqvd0026\kat -SourceDatabase dssp -sourcetable Baseline -DestinationServer hqvd0026\kat -DestinationDatabase dssp -destinationtable Scan -c -f c:\tablediff.sql
OR 
A=A-B
The following query returns any distinct values from the query to the left of the EXCEPT operand
that are not also found on the right query.
select * from dbo.baseline
except
select * from dbo.scan
The following query returns any distinct values that are returned by both the query on the left and right sides of the INTERSECT operand.
select * from dbo.baseline
INTERSECT
select * from dbo.scan
