Hello:
I have looked through these newgroups and other materials, and I just cannot
figure out why I have these networking problems.
I have a network of 5 computers, 4 of which are hard-wired, the fifth one (a
notebook) uses a wireless connection. My notebook shows a good to excellent
signal the entire time, yet, I experience these disconnects from the network.
It takes
about 10 seconds or so, and then I am re-connected again. This is a big
problem for my ability to run jobs remotely on other machines on my network.
These jobs will terminate when the network connection does.
I have a firewall installed on one of the machines that connects to the
outside world, the other machines have antivirus software, however, they do
not have a firewall. The machine with the firewall is XP Home. The other
hard-wired machines are NT4, and Win 2000 (2). The notebook with the wireless
connection is XP Professional. There is one user registered on four of these
five machines (the XP home machines has a few more since it is used by other
users as well).
The event log on the wireless notebook shows a number of errors, warnings,
and information messages. I get event 4201 which seems to appear all the time
when I re-connect after one of those strange disconnects. I get event 4319
which tells me that
"A duplicate name has been detected on the TCP network. The IP address of
the
machine that sent the message is in the data. Use nbtstat -n in a command
window
to see which name is in the Conflict state."
When I use nbtstat -n, I get this result:
Wireless Network Connection:
Node IpAddress: [192.168.1.19] Scope Id: []
NetBIOS Local Name Table
Name Type Status
---------------------------------------------
DYNAMO <00> UNIQUE Registered
DYNAMO <20> UNIQUE Registered

HIS <1E> GROUP Registered
HIS <1D> UNIQUE Registered
..__MSBROWSE__.<01> GROUP Registered
Local Area Connection:
Node IpAddress: [0.0.0.0] Scope Id: []
No names in cache
Where can I see that there is a duplicate name? There are only 5 machines on
the network. The workgroup name is the same, and I know they have different
names.
The network connections seem to be fine according to ipconfig /displaydns:
