I write this with a little embarrassment at the solution to a problem I had. Earlier this week I renamed a server I’m using for GP2010 to prepare for a new network and improve my network naming conventions. I’ve changed server names before at clients and the steps and places you need to make updates are pretty straight forward, at least for vanilla GP. There are other complications when you get into web services and other things where the configuration is not strictly within the application.

Fun with changing a server name!
