Running IIS4.0

Hi,
I’m running IIS4.0 on a winnt4.0 machine .. Is there away to stay current on security patches.I know I could go to the technet website and look for security patches there, but I’m not sure exactly where to look on the website. I was hoping that there is one web page I could constantly check maybe every other day or so for these security patches for IIS4.0. Any help would be appreciated.. Thanks in advance….
