Microsoft Windows XP With Service Pack 2

A Windows XP computer serving as a HASP License Manager may lose the ability to broadcast GTX software licenses after an installation of Windows XP Service Pack 2. The following instructions step through the process of modifying the Windows Firewall to overcome restrictions imposed by the service pack installation. The need for the firewall change is evident when, after the service pack 2 installation on the License Server, a GTX client computer displays one of the following alert messages while starting the GTX program.

To begin, access the Windows Security Center from the Start button > Programs > Accessories > System Tools > Security Center on the Windows XP desktop. From the Security Center window select Windows Firewall.

The Windows Firewall may be disabled completely when the Off selection is marked. Continue with this lesson if Off is not the desired state of security.

The Exceptions tab will reveal an Add Port control which this lesson will refer to in the following steps. Port 475 must be open as a firewall exception to allow the HASP server to communicate with remote GTX client computer software. To begin, click on the Add Port button.

For confirmation that Port 475 is safe to have open through the firewall you may perform an internet search for the following phrase "Well-Known IP Ports". Included among the responses will be lists of port number definitions which may be used to confirm that Port 475 is registered for the use of the NetHASP license service, for example:

tcpnethaspsrv   475/tcp
tcpnethaspsrv   475/udp

In the Add a Port settings window, which was opened by the previous step of this lesson, enter the following information. Type 475 as the Port number and check the TCP selection. The Name value may vary from the example.
Select OK.

Once again click the Add Port control of the Windows Firewall and enter the following to the Add a Port settings window.
Type 475 as the Port number and check the UDP selection.
The Name value may vary from the example. Select OK.

The modifications to the Windows Firewall are now complete. The Exceptions tab should display the names used during the previous Add a Port processes. Close the Windows Firewall and Security Center to test the NetHASP License distribution.
