This question came from our site for professional and enthusiast programmers.

You may want to use the .net cleanup tool and user guide

Edit: This tool removes any version of the .NET framework from 1.0 -> 3.5, inclusive of service packs. As Aaron's blog states, "It will remove files, directories, registry keys and values and Windows Installer product registration information for the .NET Framework. The tool is intended primarily to return your system to a known (relatively clean) state in case you are encountering .NET Framework installation, uninstallation, repair or patching errors so that you can try to install again."

Kind of difficult questions... I'd start by applyng Microsoft Update, then scanning the server with a good antivirus. Beyond that, we'd need more info. And yes, more of a question for server fault.

First: Make a backup of the current state. Then, if possible, try to only restore the missing files from one of the older images (it should be possible to mount an image and access it like a harddisk). If your imaging solution doesn't allow that, restore the image to a spare disk and copy the files from there.
