APPLIES TO


 * Microsoft Windows XP Service Pack 2

SYMPTOMS
Assume that you use one of the following programs on a Microsoft Windows XP Professional-based computer that is configured as a Web server:
 * The FrontPage 2000 Server Extensions for Microsoft
 * The FrontPage 2002 Server Extensions for Microsoft
 * SharePoint Team Services from Microsoft

In this scenario, your computer may not work correctly as a Web server after you upgrade to Microsoft Windows XP Professional Service Pack 2 (SP2). For example, you may not be able to connect to a Web site that is hosted on the Web server that is running on the Windows XP SP2-based computer.



CAUSE
This issue occurs if the port that Microsoft Internet Information Services (IIS) uses is blocked by a firewall. By default, Windows Firewall is enabled in Windows XP SP2.

Note Windows Firewall was previously named Internet Connection Firewall.



WORKAROUND
To work around this issue, open the TCP port that is used by IIS. For example, if IIS is configured to use the default port 80, open port 80. To do this, follow these steps.

Important When you open ports in your firewall, you increase the risk that other programs can gain access to your computer through those ports. Therefore, we recommend that you carefully consider your network security requirements before you open ports in your firewall.
 * 1) Click Start, click Run, type ncpa.cpl in the Open box, and then click OK.
 * 2) Right-click the network connection that you want to configure, and then click Properties.
 * 3) Click the Advanced tab, and then click Settings.
 * 4) Click the Advanced tab.
 * 5) Click Settings for the network connection.
 * 6) Use one of the following methods, depending on your situation:
 * 7) * If IIS is configured to use port 80, click to select the Web Server (HTTP) check box. Verify that the name or the IP address is displayed correctly in the Service Settings dialog box, click OK, and then click OK again.
 * 8) * If IIS is configured to use a different port, click Add. In the Service Settings dialog box, specify the settings and the port number that you want, click OK, and then click OK again.
 * 9) Click OK.
