NetBios over TCP/IP on NT and 95 w/Visual C++

[Brian Sulka]

I have written a Netbios application in visual C++ 4.0 using Microsoft's
Netbios Library.
-The application runs on a small dedicated network so no Name lookups etc..

-It works fine in 95.
-take the same program to NT and even though the Netbios library says that
it can be ported to NT.. I cannot add a name without getting netbios error
x34 "environment undefined reset required" (this error does not occur in
95)
-if I do a Reset as requested by the error message I get a x1F error (which
is undefined in the nb30.h file)
-I have noticed that the netapi32.dll file is quite a bit larger in NT than
95.

- can someone tell me what "environment" they are talking about and where I
can pick one up? Or Even shed some light on this message would help..

Thanks in advance for your help..

In order to use NetBIOS in NT, you need to do the following:

First, issue an NCBENUM command to enumerate the available LANAs. It is
quite possible that your NT configuration does not have a default (0x00)
LANA, so you should get the list of available LANAs.

Then, for each LANA, do an NCBRESET command (setting the ncb_lana_num field
to the correct LANA), to reset the "environment". Since LANAs may refer to
NDISWAN (or RAS/Dial-up networking) circuits, you may want to do an
NCBASTAT to check the status (look at the adapter_address field of the
status buffer) to see whether it is a RAS or NIC address (it should be
pretty apparent).

As an alternative, you can set a default LANA (I think) in Control Panel,
but you can't count on users/customers having done this, so you probably
need to assume that it hasn't been done, and use this painful process. You
have these issues in Win95 as well, but I think Win95 requires a default
LANA, so you probably haven't seen it.
