Having to install new laptops, re-install old ones, configuring virtual servers or whenever you get the opportunity to install SQL Server from scratch, you always end up with an empty list of servers, when you try to connect through SQL Server Management Studio (SSMS).
There is a way around this minor, but still sometimes very annoying issue.
The information is stored in one file only, on the profile you are currently logged on to. So copying this file, from an existing setup or a shared repository (like SkyDrive or TFS), to the new environment will bring you up to speed really quick.
The file is named SqlStudio.bin and can be found at <DRIVE>:\Users\<PROFILE>\AppData\Roaming\Microsoft\SQL Server Management Studio\<SQLVersion>
I have not tested if any third-party tools register anything in this file, so beware and be sure to have the original file ready, in case of dissaster
