is there a way to change firewall settings remotely?? for example in a remote domain from Server??

is there any command for doing such thing??

thanks

Firewall settings can be managed through Group Policy. Here's how: Managing Windows XP Service Pack 2 Features Using Group Policy

Here is also is an example of mine for allowing port exceptions via group policy
