I also decided that what you suggest is a possibility. See my email to

Thanks for phoning me yesterday. For your info, after we spoke last
night I removed and then reinstalled the TCP/IP stack and the Ethernet
card. It didn't help!
One thing that comes to mind is that the Uninstall that Nortel provided
may have been the culprit. What happens sometimes is that poor
uninstall routines delete files such as .dlls that are used by programs
other than the one that is being removed. Then once the uninstall is
executed, other software doesn't work. What install programs must do is
mark files that already exist before the installation as "shared". Then
the uninstall must not remove these.
(Of course this approach has the potential of leaving unused files
around. But these can be cleaned up with various garbage collection
programs that are available. Alternatively the new software to be
installed might never use any existing files but load all of its own.)
The way that Windows integrates their browser is a case in point. If
you remove MSIE, networking as well as other functions break. The OS no
longer functions. Microsoft was roundly criticized in the courts for
Anyway, I've already spent about 6 hours that I really couldn't afford
messing with this. I can't spend any more time. If you have a
definitive answer and fix, then let me know. Otherwise next week I will
wipe my disk and reinstall everything. This of course will take another
4 - 6 hours including all the apps and their configurations. Sigh!
I will not be available after tonight until Sunday 18 July.

The problem was not with the installed software; it was the uninstall that did you in. For some reason the uninstall wizards fail to record the fact that certain files were present before the install and tag them as "shared files" (used by more than one program). Then when the install happens, these "shared files" are removed leaving the old programs inoperable. The trick is to reinstall your networking software to restore these key files. It would be nice if we lived in a world of perfect software that always worked as advertised, but alas, we don't. But just because we have had some initial problems, we may not want to throw out the baby with the bathwater. Clearly we need more testing and some rigorous debugging before we are ready for prime time, but I think if we continue to pursue the goal we can reach our objective of getting our committee "on-!

This way there is no need to fiddle with anyone's machine above possibly changing an IP address or two. No possibly dangerous software is put anywhere where it can mess you up.
