Running SysPrep on a Virtual Machine with SQL Server Installed

This is not strictly a virtual machine tip, but a lot of people run SysPrep on virtual machines to create base images that they can redistribute, so I do hear about this a fair bit.  Normally if you run SysPrep on a virtual machine which has SQL server installed, and change the computer name in the process, SQL server will stop working (due to the name change). 

It is a little known fact is that this can be corrected easily.  The details on how to get SQL server back up and running after changing the computer name are available here: http://support.microsoft.com/kb/303774
