Each of your computers should have unique network name. To view/change the names, right-click on "My Computer" then select "Properties". When the Properties window comes up, click the "Computer Name" tab. Click the "Change" button to give it a unique name."How to change a computer name, join a domain, and add a computer description in Windows XP or in Windows Server 2003" < http://support.microsoft.com/kb/295017 >HTH, JW
