[omniORB] OmniOrb starting problem

[Po Geng]

 Hi!

Thank you for answer question. It can fix the problem.

However, disable media sense has some negative effects and may cause
confusion to users in some cases.
I tested the old version of our product (Compiled with IONA ORBacus) and
it doesn't have this problme. So there is some way to fix this problem
in Omniorb side. Can this problem be fixed in next release?

- Under XP its recommended to Disable Media Sense for TCP/IP:
    see http://support.microsoft.com/default.aspx?scid=kb;en-us;Q239924
  Use Registry Editor (Regedt32.exe) to view the following key in the
registry:

  To install the Microsoft Loopback Adapter, follow these steps:
    Click Start, point to Control Panel, and then click Add Hardware.
    Click Next.
    Click Yes, I have already connected the hardware.
    In the Installed hardware list, click Add a new hardware device, and
then click Next.
    Click Install the hardware that I manually select from a list
(Advanced), and then click Next.
    In the Common hardware types list, click Network adapters, and then
click Next.
    In the Manufacturer box, click Microsoft, in the Network Adapter
list, click Microsoft Loopback Adapter, and then click Next.
    Click Finish.
  Restart your computer.

I guess that should make it into the documentation somehow !?
