Below you will find the official word from Microsoft regarding this hotfix. I am unsure if this is common knowledge or not; ignore this email if it is... Basically, installing MS01-035 causes the IIS MMC to close when you click on the server extensions tab under Windows 2000 Advanced Server on SP2 (with all current hotfixes). Uninstalling MS01-035 fixes the problem, but opens up the security hole. This, I claim, is a broken solution. Of course, you could uninstall the hotfix, make your sever extension mods, then reinstall the hotfix, and just live with the MMC dying when you click on the server extensions tab, but this is also a broken solution. Given the publicity that unchecked buffers have been getting with respect to IIS, it seems to me that Microsoft should have a better solution... -----Original Message----- <snip useless info) Here is a summary of the key points of the case for your records.
