I've reproduced and taken a look at this one. It's not so easy to
fix. It's actually a difference in the way Samba returns a large
DCE/RPC datastream to Win9x clients. They expect things a "certain"
way (as can be seen by looking at how W2K responds to them) and
if it isn't returned that way they stop requesting more users.

It's a bug in the Win9x client code I think, but one that Win2k
works around on the server side. I'll try and examine the server
code in Samba to see how easy it is to do the same fix...

Thanks,

Ok, thanks...
I don't know if this helps you, but we tried with NT 4 and the bug was not 
there...
We have several linux boxen here. I am not a C programmer, but I'll be 
glad if I can help you someway (network dumps, trying again with HEAD ...)

We also tried setting up a Nt 4 PDC, and everything is ok...
