Checklist for auditing Domino Servers.

I look after a number of servers in a number of domains for various clients. Generally they've been built and maintained by me, or maintained for so long I know them well.
However, I've been asked by a large company to audit a couple of their servers that haven't had anyone resonsible for them so they're probably in a bit of a mess.

Could someone point me to a URL or redbook or something that has a list of what to check when auditing a Domino server, or let me know what you do? I'm basically after a checklist so I don't miss anything.
I've been a Domino admin for a few years but have never had to audit an unfamiliar environment with suits looking over my shoulder, and I don't want to get back to the office only to think, shit, I forgot to check this or that!

It's not extremely difficult but it is kind of urgent.

Cheers,

Sam.
