We are planning to deploy SP 4 for windows 2000 to our clients. What will
happen with the post-sp4 security patches that have been deployed this last
year? Will they be overwritten by sp4 or is there an intelligent file version
check built-in, so that the newest files are left untouched by sp4
installation? Or do we have to reinstall all post-sp4 sec patches after
installing sp4?
