Error 580 with w9xServerList

Question:

I'm using WinBatch 98E and the Win9x extender. I've got a program that needs to enumerate the Domain Controllers in a specified domain. My code calls the w9xServerList function as shown below.

	ResourceDCList = w9xServerList("", ResourceDomain, 24) 

where ResourceDomain is set to the workgroup/resource domain of the calling system. This call is working consistently on some systems and failing consistently on others. On those where the failure occurs all other browsing functions appear to be working normally (network neighborhood, net view /workgroup, etc.)

I'm getting an error 580 which says that no browser servers could be found. But the system is obviously able to locate the master browser for other functions.

We've spent several days troubleshooting this problem now with little progress. Any ideas?

Answer:

No real good ideas.

I always start at the Control Panel network applet and closely compare the various network settings and especially the protocols looking for differences between running and failing machines.

Generally for Browsing, I've seen that the NetBUI protocol needs to be there.
