WSUS

I am new to servers and WSUS. i am having a problem with updates. I get the error “The update cannot be approved for installation because its microsoft software license terms failed to download. click retry download to start donwload again.” I click retry and it fails still. any help would be appreciated. Also, when i started inital sync, i was getting downlaods from 2001, will these updates disappear? How can i make them? my computers already have these updates installed prior to wsus being deployed on my network. They make the list very large and make the console and system run slow when it is loading the list of updates.
