NetBIOS over TCP disabled

[Guest]

We have several machines in our network that exhibit the following symptoms:
They are Windows 2000 machines, in a mixed Win2k/NT AD domain. They are set
as DHCP clients, and the DHCP server is set to provide the address of a valid
WINS server. However, when they boot up, IPCONFIG reports that Netbios over
TCPIP is "disabled", and no WINS server is listed. They are able to browse
the Web, and they can even contact our Exchange server, but they are unable
to reach shared folders or pritners. Browsing to a server or share gives
"Network path not found", even if using the FQDN or IP address.
We have tried making them non-DHCP clients, and explicitly saying to enable
NetBIOS over TCP/IP, but they still show it disabled, and still can't browse.

This problem has arisen following some network work and a bout of viruses,
which we believe are now all gone. Is there a way to restore these machines
without reformatting them?

Go to Device Manager - Activate Show Hidden Device (in View menu) and take a
look at the Non-Plug and Play Drivers section. You should find here "NetBIOS
over Tcpip" driver. Make sure it is enabled.
Another idea would be to reapply the latest service pack (4).

No luck. NetBios over Tcpip driver is present and enabled.
I did see soemthing called NT Apm/Legacy Interface Node, which was disabled.
I don't support enabling that would help.

I'll try re-installing SP4. Thanks!

No, re-installing Windows 2000 Service Pack 4 didn't help either.

Any other suggestions, anyone?

I thought I might as well add my solution, since I paid MS Tech Support $200+
for it. Worth every penny to me, but others might find it useful too...

Using Regedit (carefully), browse to
HKEY LOCAL MACHINE / SYSTEM / Current Control Set /
Services / NetBT/ Parameters

set the value of the key TransportBindName = \Device\
Add a dword key with name SMBDeviceEnabled, value = 1
and restart the computer.

Note that this problem is probably the result of a virus or trojan
program messing with your registry. You may want to take additional other
precautions. But as a critical fix, it might work. Try it and see

Good luck!
