Hi

Does anyone know what port(s) windows automatic update uses??

I have 10 system network and a router but i only want 4 of the systems to be internet enabled...

BUT

I also want to enable all the systems to use the automatic update feature in windows to keep up to date, especially after the Blaster virus...

I thought i would use an ACL to block all ports except those used by windows update, (if it uses port 80 then i wont bother:eek:)

Thanks for the help

If you just want to block WindowsXP uncontrolled Internet interaction (including Auto Update). This free and very simple program is an excellent tool.
