How to Change the Host Computer Name on W2K3R2 SQL 2K5 Server?

I am having some application issues installing an Ultipro Server on W2K3R2 w/
SP2 and SQL 2K5 w/ SP1 when the Host Name was changed after SQL was installed.
I saw a post about this and thought there should be a good way to check and
fix?
Hi
If SELECT @.@.SERVERNAME returns the old server name see:
