Hi.

One of our customers made silly things with his computer but I can't find a way to recover it.
Maybe one of you has already run into the same problem.
Here it is:

The system installed and runnin was Windows 2000 Pro SP4.

He did some "cleaning", then had problems and tried to reinstall it with his original Windows 2000 Pro Upgrade (no SP) cd.

Now, after the first reboot, the system shows an svchost.exe error and the installation hangs up at the "hardware detection screen".

Or, if I restart the computer in safe mode, the installation goes further but starts generating errors message as follow:

iccomplusore.cpp (line 274)
error code = 0x80040206
COM+ event classes could not be registered

Install continues but at the "registering components" (so close to the finish line...) I receive an error message which is:

c:\winnt\system32\inetcomm.dll cannot be registered

Then, system hangs up.

To be clear:

- I've removed the hd and scanned it for virus on another PC with an up-to-date NAV: no virus. I even downloaded the blaster removal tool and scanned the hd: nothing found.

- I've installed a parallel fresh copy of Windows 2000 on that computer: it works fine. (The reason why I don't use that one is that the customer doesn't want to loose his work domain access configuration.

So guys, any idea?
