NETBIOS Problems

By Olle Felten ·
I have an application which use NETBIOS for LAN communication. When installing our app in preinstalled Win 2000P computers, the NETBIOS (NETBIOS activated over TCP/IP) traffic will not work properly.

We can solve this problem by formatting the harddisk and reinstall WIN 2000 P. another way is to uninstall all netwokr components and then reinstall them. Nobody I have asked have been able to explaine what, exactly, ?s the reason for this behavior. I would, very much, appreciate to get to know what this realy is about.

I think that it must be able to solve the problem in an easier way than reinstall everytime we shall install our app.

Can anyone help me?

Hi,
Just a thought, but on your prebuilt machines, in the tcp\ip properties advanced section, look on the wins tab and ensure that the 'disable netbios over tcp\ip' is not checked. Hope this helps...

We have checked this, and it?s not the problem.

NETBIOS Problems

If I am hearing you correclty is,

"Every time I install a particular app, it breaks NetBios"

You have basically answererd your own question.

The problem here looks like the app you are installing is "rewriting/replacing" the 2K NetBios protocol. The only way to get it back to it's original state is to remove/reapply the protocol. When you remove it and reapply it, 2K uses the one it owns to replace it, not the one your app used.

So the answer here is, 1. not to install the app, 2.If you install the app, can it be customized not to install network components 3. Or deal with it and treat it as a known bug.

You know how to fix it and can document it in the install instructions for future people to rely on who step in for you.

The other option is to contact the vendor and see if they have a solution.

My application does not install any 2k Netbios protocol, so it can not be the solution. The problem does not show, when the app is instaled in a machine with another Windows version, and not when Win 2k not is preinstalled from the distibutor.

I have asked Siemens technical support, and they know about the problem. They say that it is a general problem with Win 2k. They say that the problem is dusicussed with Microsoft, and theire answer is that it is a hardware vendor problem.

We have had the problem with other machines than Fujitsu Siemens too, so it is not a Siemens problem, as far as I can see.

I will try to re-explain....

The app is not installing 2K netbios,.. which is the problem.

So you install it on a win98 machine, and it works fine. But you install it on a 2K machine and it does not.

The protocol implemantaion used by 2K is different then the one used by win98. If the app is installing one that is "win98" or even updating it, then it will break 2K.

Proof of concept. Wsock32.dll, is a pretty standard dll that IE uses to load up. It is common among all M$ OS's. However, if you extract Wsock32.dll from win98 and place it on the desktop of 2K, your browser will fail to work.

Why? The Wsock32.dll file from Win98 is a different implemantion then the one for 2K.

This is what is happening with the app you are installing. It is updating a component with one that was not made for 2K. Which is why removing and reinstalling the protocol fixes the problem.

Thank you for your answer, but I can?t see that you have focused the right problem, since we do not have the problem when we install a W2K computer from scratch and then install our app. There is, of course, a possibility that the WSOCK32.DLL is configured differently when you install W2k from scratch than it is while the distributures install there versions?

I?ll try to find some information about that. Perhaps you have some ideas about where to look? Thanks, anyway!
