Client computers that run Windows Firewall might require exceptions to be defined to allow communications with Microsoft System Center Configuration Manager 2007 site systems. These exceptions vary depending on the features of Configuration Manager 2007 you intend to use.

The following sections list the features of Configuration Manager 2007 which require exceptions to be made on the Windows Firewall and provide a procedure for configuring these exceptions.

Modifying the Ports and Programs Permitted by Windows Firewall

To modify the ports and programs permitted by Windows Firewall:

  1. On the computer running Windows Firewall, open Control Panel.

  2. Right-click Windows Firewall and click Open.

  3. On the Exceptions tab of the Windows Firewall Settings dialog box, select enable any required exceptions in the list box, or Click Add Program or Add Port to create custom programs or ports

Programs and Ports Required by Configuration Manager 2007

The following Configuration Manager 2007 features require exceptions to be made on the Windows Firewall:

Queries

If you are running the Configuration Manager console on a computer running Windows Firewall, queries will fail the first time they are run.

After failing to run the first time, the operating system displays a dialog box asking if you want to unblock statview.exe. If you unblock statview.exe, future queries will run without errors. You can also manually add statview.exe to the list of programs and services on the Exceptions tab of the Windows Firewall prior to running a query.

Client Push Installation

In order to successfully use client push to install the Configuration Manager 2007 client, you must add the following as exceptions to the Windows Firewall:

  • File and Printer Sharing

  • Windows Management Instrumentation (WMI)

Client Installation using Group Policy

In order to successfully use Group Policy to install the Configuration Manager 2007 client, you must add File and Printer Sharing as an exception to the Windows Firewall.

Client Requests

In order for client computers to communicate with Configuration Manager 2007 site systems, you must add the following as exceptions to the Windows Firewall:

TCP Port 80 (for HTTP communication)

TCP Port 443 (for HTTPS communication)

Important
These are default port numbers which can be changed in Configuration Manager 2007. For more information, see How to Configure Request Ports for the Configuration Manager Client. If these ports have been changed, you must also configure matching exceptions on the Windows Firewall.

Network Access Protection

In order for client computers to successfully communicate with the system health validator point, you need to allow the following ports:

  • UDP 67 and UDP 68 for DHCP

  • TCP 80/443 for IPsec

Remote Control

In order to use the remote tools features of Configuration Manager 2007, you need to allow the following ports:

  • TCP port 2701

  • TCP port 2702

  • TCP port 135

Remote Assistance and Remote Desktop

To enable Remote Assistance to be initiated from the SMS Administrator console, add both the custom program helpsvc.exe and the custom port TCP 135 to the list of permitted programs and services in Windows Firewall on the client computer. Also, Windows Firewall must be configured to permit Remote Assistance and Remote Desktop. If a user initiates a request for Remote Assistance from that computer, Windows Firewall will automatically be configured to permit Remote Assistance and Remote Desktop.

Windows Event Viewer, Windows Performance Monitor and Windows Diagnostics

To enable Windows event viewer, Windows performance monitor and Windows diagnostics to be accessed from the Configuration Manager console, you must enable File and Printer Sharing as an exception on the Windows Firewall.
