Unsolvable NetBios Problem

I have searched a lot on the web, tryied thousands of solutions and
none works.
Here is a list of symptoms and information :

Symptoms :
- Unable to ping computer names on LAN
- Able to ping computer IPs on LAN
- Unable to browse files on LAN Computers
- Unable to list LAN Computers
- Unable to map network drives

Tests done :
- After clicking "repair" for the network card, error shows : "...
follwing action could not be completed : Clearing NetBT"
- After entering "nbtstat -r" in the CMD, it shows error : "Failed to
access NetBT driver -- NetBT may not be loaded"
- After entering "ipconfig /all" in the CMD, I get "Disabled" for the
status of "NetBios over TCPIP"
- Tryied reinstalling the network card driver
- Tryied rebooting
- Tryied rebooting all the network devices (switch, rooter etc.)
- Tryied using other sockets of the switch (ones that surely work)

Current configuration of the system :
- Windows : XP Pro English - SP2 (up to date)
- User account : Computer Administrator
- Antivirus : stopped
- Windows firewall : stopped
- IP Address : 192.168.1.*** (no IP conflict, tried over ip addresses)
- WINS : LMHOSTS lookup : checked (enabled)
- WINS : Enabled NetBios over TCP/IP : checked (enabled)
- All DNS parameters are good
- Registry value for NetBios>Start : 1
- Registry value for NetBT>Start : 1
- Workgroup name is good


Thank you very much for your answers

These are suspicious, and tend to indicate that either the relevant services
failed to start, or perhaps you have a broken TCP/IP stack.

Check in services.msc to see if the Server and Computer Browser services are
running. These are both necessary for netBIOS name resolution to work.

You might also like to get hold of LSPFix, which will tell you if an
impostor 'shim' has been inserted into the TCP/IP stack, perhaps by malware.

You might also like to try issuing:

net use h: \\192.168.1.23\sharename /user:username

at a cmd prompt, to see if you can access a share directly by IP.

As Antaeus suggests, you may well have an LSP / Winsock / TCP/IP corruption
problem.

How did you stop Windows Firewall? What antivirus protection package do you
have? Look for antiworm protection, that won't shut off with the antivirus.

You could try to diagnose the problem, using logs from "browstat status",
"ipconfig /all", "net config server", and "net config workstation", from each
computer. Read this article, and linked articles, and follow instructions
precisely (download browstat!):

Services "Computer Browser" and "Server" are working ans started.
I have Kasperksy 6.0
I shut the windows firewall by going in the control panel>windows
firewall
I have full access to internet.

Shutting the antivirus and the firewall seem to change nothing to the
problem.

Kaspersky also has anti-worm protection, which isn't part of the firewall, nor
the anti-virus. That will block SMBs too.

So you are suggesting I should uninstall Kasperky ?

Kaspersky Support, or the user guide, should be able to direct you to the right
setting for the anti-worm. If you can't find it, though, un installation may be
the next best choice.

Indeed Kaspersky seems to be a problem, I have trouble uninstalling
it... I don't know if its the cause of my network problem but there is
surely something strange I didn't expect with kaspersy.

As with most anti-virus systems, the inclusion of an Internet worm
protection module will break the network browsing by PC name. You can
confirm this by trying to broswer you network by the IP address of
another PC. If you can see the other PC by IP address, then you need
to look at the anti-virus system advanced setting so as to configure
the Internet worm NetBios scanning rules to allow your LAN to be
seen. Most "off the counter" anti-virus systems tend to "assume" that
the PC is only accessing the Internet. Corporate versions seem to not
have the assunption.

Worm protection (INTRANET) will interfere with SMBs. This may include:
1) Name resolution ("netbios-ns" aka "browsing by name").
2) Resource enumeration ("netbios-dgm" aka browsing, period).
3) Resource access ("netbios-ssn" aka file sharing, period).

Every different anti-worm system, which protects the computers on the LAN from
each other, will have different peculiarities.
