Hi all, Hi Alin after my last mail you asked to describe the settings of my network more precisely, a bit late but now I will try to do that. The problem is that the samba server doesnt get the master browser with the following brrwsing options and I think that this causes the unreliable browsing within the workgroup. local master = yes preferred master = yes domain master = yes os level = 64 With nmblookup -M - -T I see that allways one of the win98 clients is the master browser. Now the more complicated part. My workgroup is a part of big network with a DNS and DHCP server. The IP adress is provided from a central DNS server. If I execute nmblookup '*' -T I see that samba resolved the name of the clients with their DNS names and these are different from their netbios name. I added a lmhosts file (on client and server side) but this doesnt change anything. winipcfg showed that the clients use dns to resolve netbios names, i changed the registry, but that had no influence of the output of nmblookup. I noticed that another samba server in the network acts as wins server, so i add this adress to my server (without wins support) and setup the clients to use this wins server, with no succes. After this i changed the name resolve order (more ore less in the try and error style, but so far I achieved more errors). Any suggestions what I can can try to solve this problem? Thanks in advance Arne
