services.exe is just a shim app that hosts your Services!
In Administration Tools (in your control panel on W2K Pro and on your main menu on Sever), you will find a Services MMC snapin. Fire it up and look at your running services. Lots of them will be Started Automatic and you can shut some of them down that you don't need. For example you might not need IIS or SNMP servers running that will touch your internet connection.
