The PNA Series and Windows XP Service Pack 2


 

Important Information Regarding the PNA and Windows XP Service Pack 2
xp (2K)

XP Service Pack 2 was released On Aug 6, 2004. Agilent is now beginning to incorporate this change on newly shipped instruments. Users with XP already installed on the PNA can update to SP2, but they should be aware that it will slightly affect operation of the PNA. This page will describe some of the proper settings to ensure the PNA works properly. A small utility program is also provided to make the required changes automatically.



Installation Observations:

  • Installation time is almost exactly 1 hour
  • During installation, the progress bar seems to stall at about the halfway mark until installation is almost complete; this is normal.
  • After initial boot, you will be presented with a Security Center set-up window that is bigger than the screen size; you will have to use the scroll bars to access the "Next" button to continue.
  • After installation, the hard drive will be somewhat fragmented. You should run the built-in Windows Disk Defragmenter tool.

SP2 Known Issues

The built-in firewall of SP2 will automatically be turned on as default. This will prevent DCOM and Intuilink from functioning. If you need to communicate with your PNA via DCOM or Intuilink, you can either disable the firewall (not recommended), or make changes described below.

The ability to use the co-initialize security method with DCOM in order to avoid the requirement of users needing an account on the PNA will also stop functioning. The additional changes listed below will also need to be made to regain access to this feature.

Once these changes have been made, the DCOM and Firewall settings will then match the configuration of the PNA as it is now being shipped from the factory.

The XP Security Center feature of XP SP2 will complain if no antivirus software is installed. This can be ignored, but it is a good idea to have some form of antivirus active on the PNA. Agilent uses Symantec's antivirus on PNAs within the factory, so we know that this brand functions properly with the PNA. Other antivirus programs (such as McAfee and Grisoft's AVG) will most likely work as well.

Detailed Instructions for Configuring the XP Firewall and DCOM Settings

You can either make the below changes manually, or download and run this SP2 Modification Utility on the PNA (updated Feb 7 2005)

Recommended XP Firewall Setting to Allow DCOM, SICL, and Intuilink Capability

  1. Close the PNA application
  2. Click on Start, Settings, Control Panel, Windows Firewall.
  3. Click on the Exceptions tab
  4. Check the box labeled File and Printer Sharing. Recommended, but not absolutely required.
  5. Click on the Add Port button
  6. Add a name of RPC Port and a port number of 135
  7. Click on TCP and then OK
  8. Click on the Add Program button
  9. Click on the Browse button and navigate to the following directories. Individually, add each .exe program listed.
    • C:\Program Files\Agilent\Network Analyzer. Add 835x.exe
    • C:\Program Files\Agilent\Network Analyzer. Add pnaanswerserver.exe
    • C:\Program Files\Agilent\IO Libraries\bin. Add portmap.exe
    • C:\Program Files\Agilent\IO Libraries\bin. Add siclland.exe
    • C:\WINNT\system32. Add dllhost.exe
  10. When done, click OK to exit (the OK button may be just below the bottom of the screen)

Note: You may also want to add any other programs to the firewall exceptions list that require remote access (such as VNC server). If you do not do add it now, any program that requires remote access will display a warning message when access is first attempted. At this message prompt, you can then choose to either allow or deny permission.

This completes the XP Firewall settings.
