I have a project where multiple developers are using a copy of the same windows Virtual PC image (W2K3 SE SP2). Because our solution is tied to the machine-name (less than ideal, i know) all of the developers have the same machine name.

We use a VPN to connect to a remote system, upon connection we get the ‘Windows Error: A duplicate name exists on the network’ error.

Since all development is happening locally, we’re not dependent on other machines connecting to us — only outbound connections.

I know it’s best practice to change the machine name, but what’s the reasoning behind this? What impact would this have?

  1. If you are doing all work locally on the VM, there is no reason why the machine name needs to stay the same.

    I have run into a similar situation where I work. We were using Microsoft’s trial version of SharePoint 2007 VM. Same error, no issues with development. The only thing I ran into was when I opened Internet Explorer to view the pages on the server by typing http://servername/page.aspx, I would hit another developer’s VM. I had to use http://ipaddress/page.aspx to hit my own machine.
