windows 2000 sp3

ok, let me making it known, i hate this service pack, but i am stuck with it.

does anyone have any experience with this problem. did not happen to me till sp3.
i go to the windowsupdate website. download the ciritical patches. and whammo.....i start getting event id 1000, userevn error. cannot unload roaming profile.

it does not stop till i take off enough hotfixes and sercurity patches to make it happy. this has never happened to me till sp3....and its making my life quite difficult!
i've been thru the microsoft website, looking for this error. found several versions of it, but going thru their lists of files, mine are all updated beyond what they tell me i need.....
