Looks like you have a web server listening on port 80 (Microsoft Personal
Web Server perhaps?), a Microsoft SQL Server listening to port 1433 (using
a database for your web pages?), you are checking your mail on port 25,
ports 135 to 139 are being used for your dial-up connection (or whatever)
and it looks like you have File and Print sharing enabled and turned on.
