one thing you might want to do is just uninstall your modem and let the computer re-detect it.... uhm.... shouldn't need to update drivers i don't think..... but i know when i installed SP2 my sound card mysteriously stopped working, so i just uninstalled it from the device manager, let my computer re-detect it, and it has worked fine ever since....

here are drivers for the Aztec v92 modem in case you need..... http://support.mpccorp.com/apps/filelist.asp?ID=7767

(if u have any questions or not sure how to do this you can send me a message )
