Configuring the firewall to allow WMI connection

WMI connection through the Real-Time view can fail when you try to connect to
a computer with Microsoft Windows XP Service Pack 2, Windows Vista, or Windows
7 operating system.
This issue can occur when the default configuration of the Windows Firewall
program blocks incoming network traffic for Windows Management
Instrumentation (WMI) connection. For the connection to succeed, the remote
computer must permit incoming network traffic on TCP ports 135, 445, and
additional dynamically-assigned ports, typically in the range of 1024 to 1034.
You can resolve this issue in one of the following ways:
Configure the firewall on the computer you want to connect to.
See "Configuring the firewall on a single computer"
Configure the firewall on all computers in the domain using group policy.
See "Configuring the firewall on multiple domain computers with a group
policy" on page 65.
Temporarily disable the firewall.
See "Troubleshooting connection through the Real-Time view"

For evaluation, you can configure the firewall using the computer s local settings.
