If you are Installing on Windows XP with Service Pack 2 (SP2)

If you intend to host a USoft Web application or use USoft Rules Service on a Windows XP machine with Service Pack 2 (SP2) installed, you must configure the SP2 firewall. You must open a TCP port in order to allow Internet Information Services (IIS) to pass the firewall. To do this:

1.	From the Windows XP Control panel, choose the Administrative Tools option and double click on Internet Information Services (IIS).

2.	In the left-hand pane of the Internet Information Services (IIS) Management Console, navigate to the Default Web Site.

3.	Click your right mouse button on the Default Web Site item, and from the resulting context menu choose Properties.

4.	Check, and remember the value for TCP Port (default = 80).

5.	Close the IIS Management Console.

6.	From the Control Panel, open the Security Center, followed by Windows Firewall.

7.	In the firewall manager, click the Exceptions Tab and press the Add Port button.

8.	Type in a name (IIS) and the port number obtained in step 4 above (default = 80).

9.	Choose the TCP radio button and click OK.

On many occasions USoft programs may try to access the Internet, for example, when opening a Web page on the Internet or when establishing a TCP connection to another computer. On these occasions the XP2 firewall will prompt you to allow the USoft program access and the program will run without any difficulties.
