Update on what I've changed.
Today, I disabled Netbios over TCPIP on ONE of the two NICS. Rebooted =
all machines, and all are still able to see shares off of the server. I =
also saw a big increase in transfer speed to/from the server. I've been =
moving some large files around (full resolution CD Audio files), and =
noted that transfer over our 100mb network was agonizingly slow going =
only to the server. Transfers to other machines on the lan were about = as
fast as I would expect. I suppose the two NICS seeing each other, = that
was causing the error I was seeing, could have been doing something = to
slow things down. Not sure, the only way to know would be to = re-enable
the second NIC for netbios and try again.
Since we only have 3 computers still on the lan running Win98, I've =
thought about just loading HOSTS files on those three machines, since =
they only need to get to the server (no access to other workstations on =
the network). Then put in a Hosts file on each machine that defines the =
server, and split the machines between the two IP's for the server, sort =
of a poor mans load balancing act.
There are probably some serious holes in this theory, so I've got the =
bullet proof vest on to take the shots .

First off, these are two different things.
NET USE and NET VIEW only require that name resolution is able to =
resolve the server name. Likely you are using broadcast resolution so = as
long as the server to which you are attempt to connect is located = within
the scope of a network broadcast the name can be resolved and the =
connection attempt can move forward.
The network neighborhood, in a non-domain environment, there are =
two different schemes. One is where each server is configured to =
broadcast it's presence and each client listens to the broadcasts and =
maintains its own list of nearby servers. These broadcasts are disabled =
by default in Windows and have been for many years. There is a checkbox =
somewhere to enable this that makes reference to LAN Manager 2.0 =
compatibility. The other scheme is using browser masters. Using an =
election process one machine on the subnet is designated as the master =
browser and it maintains the list of all servers. When your client = wants
to view the network neighborhood it queries the browser master for = the
list. If the master goes off line the other machines eventually = notice
and a new master is elected. It can then take a bit of time for = the
master browser list to repopulate. There are options to control = whether
or not any particular machine is allowed to be a browser master. =

I like this discussion. Rich, why at certain times in the middle of =
the day, I will lose access to browse the domain, BUT, form a command =
prompt, I can do Net View \\server, net use \\server\resource, etc. = When
looking in the workgroup, I only see my local machine.
Same question for a Win98 machine. I can select "Log On Domain", =
provide the Domain name (same as other Win98 machines on the Lan), and =
enter a valid user name and password, the Domain is properly filled in, =
and get a "No Domain Controller was available" error message.
So, I = switch to a NON domain login, using the Domain name as a Workgroup.
I = get logon to the local machine, AND network connections that were set
to = re-connect at logon re-connect (I've remapped My Documents to a
network = folder unique for each user), but there are NO computers visible
in = Network Neighborhood. Same thing though, from a command line, I can =
access the network resources. When using Network Neighborhood, I get =
"Network unavailable".
I did a full re-install of Win98se today on the current machine =
that's giving this problem. Using DHCP, only TCPIP loaded as a = protocol,
and set as the Default Protocol.
Very odd.
Any light that can be shed would be appreciated.
TIA

You don't need or want NetBEUI. If you have no centralized =

For name resolution, run IPCONFIG /all on both machines and =

The network neighborhood behavior is something else. For that =
