Firewall blocking remote commands

when I issue the shutdown /i command it does not work for computers that have something in the firewall enabled. I am not sure what it is but when I disable the firewall it will allow me to remotely reboot the pc.
Other comps that have the firewall enabled I am still able to remotely reboot.

Any ideas?

I'll post if I find it first :)

I think it requires remote registry and maybe WMI as well.  Services may not be running

Doing this worked: Not sure if it was the same ports you mentioned but this allowed me to remotely shutdown/manage. Now I just have to deploy this setting via gpol

Remote registry is only needed to access the registry remotely.
The issue was narrowed by the asker: when
firewall is enabled, remote shutdown fails.
Firewall disabled, remote shutdown works.
meaning all relavent service are running, but we're being blocked.

this was remote administration that was enabled. not for registry.
Remote administration is tied to ports 135 and 445.

Is there something common to these systems, OU, site?  There you can find the GPO/GPP setting the firewall policy.

they are all in the same OU. So I can set that policy within there without having to run this comnmand on a startup script or anything?

I was unable to apply the gpol since I am server 2003 administering windows 7 pc's. I will have to add this too comps via command line but it does worksy.
As long as you loaded and updated some, installing RSAT, group policy management on the windows 7 to remotely manage/administer the GPO, those options might become available to you.
