Re: Doncha hate it...
I aim to get instructions down to a single page of A4 so it doubles as a checklist you can tick off as you go (or fill in details, eg user's name, user's logon name, user's email address, etc), and anything that's too long to fit as an aide memoir is referenced to supplementary sheets. Once you've gone through it a few times ticking off while refering to the supplementary sheets, you only need them for occasional reminders.
So, eg:
Update A/D user details with (see D):
name, building, address, email address, change password:Yes
With D saying something like:
Start->Admin Tools->Active Directory Users and Devices->RunAs->your admin ID
View -> Turn Advanced Settings on
blah.thing.uk->North->Yorkshire->(site)->(user)->Menu:Properties
General: name, job title, site
Address: site address
Account: etc etc etc (I'm working from memory)
Most of the time once you're familiar the two lines in the checklist is enough, but every now and then you have a brain fart and think: where's the proxy address? WTH is it???? Check notes, ah! Dammit, need to bloody turn bloddy advanced bloddy view on.
