AFAIK, Dave does not work for Microsoft but he is very knowledgeable. If
you are quoting him correctly, then he and I disagree about Safe Mode.
I don't use NIS, but Norton Antivirus, other antivirus programs, and
spyware removal tools all work in Safe Mode. I do all my diagnostic
scanning and cleanup of clients' machines in Safe Mode.

I can't possibly untangle what you've done in a newsgroup post. I would
suggest setting everything back to default and testing from there,
adding one thing at a time. If you are not sharing files and printers,
that option should be disabled. If you do not have network with older
MS operating systems on some of the machines, you do not need to have
netbios over tcp/ip.

I can't comment on any problems you had with System Restore and NIS,
although I don't see why the combination of the two would matter. I
don't particularly like NIS, but if you have problems with it you
should contact Symantec tech support. System Restore, while certainly
not meant to be used as a backup solution, can be very helpful in
untangling messes - just like the one you've apparently gotten yourself
into. It is, of course, always your choice, but I would not disable
System Restore on a home user's machine.

There are new vulnerabilities in IE that may allow a malicious party to
take control of your computer when you visit a particular webpage. A
symptom is that the Internet Zone is turned into the Intranet Zone,
which of course has lowered security, so that your computer now belongs
to the bad guys.
There is no way I can give you an accurate diagnosis in newsgroup
postings as to whether your computer has been hacked, nor should you
rely on newsgroup postings alone to plan your next move. With that
caveat, based on your previous posts, I believe you should consider a)
having a local professional come onsite to look at your network; or b)
disconnect from the Internet and the lan and thoroughly examine and
clean all computers. If you find that any computer has been
compromised, I would format and clean install whatever operating
systems you are using and restore data from backups.
Good luck,
Malke
