Hi, Michael!
It's a password authentication problem, and not a Mac
problem: Both the PC
and Mac versions of Eudora 3.x exhibit this problem. You need to go back
into the Exchange settings and enable clear text passwords, should you
choose to do this. Note that this can represent a security loophole, though.
The problem is that Eudora 3.x supports certain encryption
protocols, and
Exchange Server supports others... And they are mutually exclusive.
I *think* Eudora 4 allows encryption that matches up with
Exchange; or you
could use Outlook for Mac bloatware, or Outlook Express for Mac if you
don't want to compromise on the security.
Lastly, how many users do you have on your Exchange server? If you have
less than 100 users; or if you don't have a full time system admin who can
keep an eye on it, Exchange is too much of a hassle. Check out EIMS 1.x &
2.x (Eudora Internet Mail Server, formerly known as Apple Internet Mail
Server) instead: It's easy to set up and maintain, but it lacks the
redundancy that Exchange offers. I wouldn't hesitate to run it on a network
of up to about 200 users with a Quadra 650 and System 7.5.1 or MacOS 7.6.1.
Cheers!

Yes! If you are connecting the machines together with ONE cable, not
using a hub, it has to be a CROSSOVER cable. Available at any CompUSA for
about $12.
Next item. Macping is a great little utility to see if TCP/IP is bound to
your network card. Make sure both machines have correspoinding IP
addresses (the first 3 octets, [groups of 3 digits] have to be the same
and the last ine has to be different. And you subnet mask has to be
absolutely the same. This is asuming you're using a Class C address which
is the most common one). DAVE uses NetBIOS over TCP/IP, not NetBUEI so
you need to set up both mahcines with valid IP addresses.
Get Macping (available at a lot of places, email me directly if you can't
find it), then give your NIC an IP address and try pinging that IP
address. IF it pings, TCP/IP is successfuly bound to the card and you
should be good to go...

See my earlier post on the host file for the Macs... Basically, you can
use it but they have to be FQDN (Fully Qualified Domain Names) that
actually exist on a DNS server. If you have an internal DNS server,
before you hit the firewall, great. If you need static IP addresses, just
do reservations on the DHCP hosts. They probably they tell you you need
static addresses because all traffic is hitting the firewall and then
going out with a single IP address, then when it comes back to the
firewall, the firewall needs to know whom to serve that request to, so if
you've changed addresses and don't have a host name, it won't know whom
to give it to.
Your best bet is to probably reserve those addresses on the DHCP server...

Maybe I missed this thread somewhere along the line, if so I apologize. I
am wondering how the predominately wintel CIH virus effects Macs running PC
cards (Orange, etc.) and Windows software emulators (Virtual PC,
SoftWindows). Is there anything to worry about, or they at risk as much as
real Wintel machines?

I am a technology specialist at a school in Milwaukee and I am trying to
allow six Hewlett Pack Vectra VL computers to share a Deskjet 870 (machines
are running win 95.) The HP's all came w/ a factory installed Network
Interface Card from 3 com and the "Device Manager" shows that the machines
are seeing the card. Do the drivers usually come pre-installed when a NIC
is pre-installed? The drivers for the NIC appear to be installed already.
I have them linked to an Asante 8port Friendly Net Hub. The printer is
connected directly to one computer and "Printer sharing" is turned on at
that one station. All of the green LEDs are showing at both the hub and
the back of the computers. Each computer has a unique identity and they
all share the same workgroup name. When I go to Network Neigborhood, I get
an error message saying "unable to browse the network." Should all of the
computers on the network show up in Network Neighborhood with their
computer name? I want to set up similar workgroups in the other seven
classrooms that have the same hardware configuration. Please help!!

Dear Don,
First off, take a look at the following article...
<http://www.theregister.co.uk/990426-000006.html>
Now, on to DOS on Mac solutions...
We need to break them out into two categories: Hardware cards
and software
emulators.
Hardware cards are just as susceptible as a standalone pee cee, because
they too have a BIOS ROM. FlashROM is susceptible to CIH, while EEPROM is
not. Whether it is FlashROM or EEPROM depends on the model... Anyone?
Software emulators are also susceptible to *some* virii; but
it's easy to
"flush the toilet" and throw away the drive container.
What you need to keep in mind is that antivirus apps will
intercept most
all virii; and with the Melissa scare many people updated their antivirus
software with the latest definitions, so they picked up the CIH definitions
as well.
Surf safely,
Dan

Actually, they are looking for the hostname to be static, and to
use that as an authorized username for the firewall.
On the PC side, they appear to be using the "Computer Name" under
the "Identification" tab in the Network control panel.
This sounds similar to the "Network Identity" section of the File
Sharing control panel on the Mac -- but I don't know why they are
unable to use this information, unless it is *not* passed over
TCP/IP. Is this available over AppleTalk only? I'm running OS
8.5.1, Open Transport 2.0.2 and TCP/IP 2.0.2.

Let's slow down a minute and check the fundamentals.
First off, do you have File Sharing enabled on the windoze box(es)?
Without this, they will not show up in the Network Neighborhood.
Second, if the card came in the box, then the drivers are also usually
installed. You can check the Device Manager to verify that the NIC has been
detected and the driver has loaded and is working properly.
Third, check your TCP/IP settings. Alternately, for
peer-to-peer you can
load NetBEUI, which is about the fastest protocol going... But it's
non-routeable, so you'll still need IP for internet connectivity.
Lastly, follow the Link and Activity LED's on the NIC and
hub... This is
how you can easily diagnose wiring problems.
Hope this helps!
