When you are setting up TFS through Visual Studio, and are trying to map a drive, TFS may give you an error saying that you can’t and that profile exists on the TFS server. It may be because the account+computername+workspace (they’re all bound) is already on the server.
The way around this is to rename the machine. This may have happened because the virtual machine was copied.
Be aware: IF YOU DO THIS, other programs that have the computer name saved to it under privileges, like SQL Server, may have to be changed. In SQL Server, you may have to login via the sa account or through single-user mode.
