db2

I think this is a fairly well known problem, but I haven't found a really solid solution to add to my toolbox.

Here's the sequence of steps that leads to the problem:

Install Windows (e.g., XP), naming the system XXX
Install DB2 and create some databases
Rename the system from XXX to YYY (via the System control panel's Computer Name tab
Reboot and find DB2 unable to start

How can I get DB2 up and running again without having to reinstall it and without having to rename the system back to XXX?

I did find a blog post that hints at some registry values to tweak, but I'm hoping the SF community can come up with a solution in which I can have more confidence.
