So there was a big rollup hotfix released for WSS 3.0. And maybe you're thinking you should just install it because, well, it's got to be good.
Before you do, consider this:
- It cannot be uninstalled.
- The hotfix will, somehow, be wiped should a service pack be installed, along with the fixes it applied.
- It has problems with host headered site collections, search, and on SBS, restarting the sites themselves properly.
Don't believe me? Read it yourself (and more) at http://support.microsoft.com/kb/934525/.
Before you install a hotfix/update/service pack always check the known issues to see if it is worth the risk, or if it breaks more than it fixes. Now you know.
If you installed the hotfix that updated WSS so that it stopped secretly sending information to Microsoft about your server without your permission, then it is possible that, after installing the Oct. 9 hotfix, your sharepoint site will completely cease to function. It will look like a database problem, but no database fix will seem to work. If that's the case, you need to uninstall the 932091 update, then reinstall it.
