Automatically Login to TFS from a VM

OS: Windows Server 2008

In order to automatically login to TFS from a machine that is not part of the network's workgroup, we need to manually specify a user credential.

Go to: Control Panel > User Accounts > Manage Windows credentials

Now add a new Windows Credential

URL: tfs.example.com This is the URL you use to connect to TFS.
Username: WORKGROUP\user.name
Password: ********

Save it, and now you should never be prompted by that pesky TFS login window again.
