So why do I urge caution on .net patches? Because they have historically had issues getting installed so that you have to uninstall them and reinstall them to get them patched… because sometimes you have to use the windows installer fix up to fix them …and lastly sometimes they “update” your web sites to a newer version of .net that they aren’t supposed to be on.
After you install these .net service packs, run the www.sbsbpa.com and ensure the RWW and the default web sites of SBS stay on version 1.1.
