server not visible anymore

[rob at network.de]

Hello everyone,

I used samba 1.9.x before and everything was fine. The samba 
server lived in some local network and I could see it from my NTbox 
as well as from Win95/98 clients.

I upgraded to version 2.0.3 and now my server is gone though I use 
the same smb.conf file which is pretty basic. I can connect to it 
using the "\\server\share" convention and can also see it when I do 
a "search computer". When the computer is found I can bring up a 
explorer window in which I can see it and all the shares, printers 
etc. but strangely enough after about a minute or so the server is 
not visible anymore. To mount a share automatically at startup 
does not help either. There is no wins server or domain server in 
the network.

Help is greatly appreciated.
