I have a Windows 2003 server that has two updates it has downloaded but will not install (each time they fail with utterly useless explanations). I want to try downloading them again in case the install files are corrupted, but each time I go to Windows Update it sees them already there and will not download them again. (These updates appear to only be available through Windows update.) Is there a way to erase them off of the server such that I can download them fresh? If so then how?
