When I first startup smb service smb restart nmbd seems to be starting up correctly. nmblookup -M chemistry querying chemistry on 128.148.nnn.255 128.148.nnn.server's-ip chemistry<1d> and nmblookup -B SERVER __SAMBA__ querying __SAMBA__ on 128.148.nnn.server's-ip server's ip __SAMBA__ <00> This quickly changes to nmblookup -M chemistry querying chemistry on 128.148.nnn.255 some client's ip chemistry <1d> nmblookup -B SERVER __SAMBA__ querying __SAMBA__ on 128.148.nnn.server's-ip name_query failed to find name __SAMBA__ I tried using the same smb.conf from samba3.0.9. I have tried and am still trying minor modifications. For instance I changed interfaces = 128.148.nnn.nnn/24 127.0.0.1 to interfaces = eth0, lo bind interfaces only = yes I added remote browse sync with the subnets which the server is used. Is there a simple solution? Should I downgrade to 3.0.9 if I can? Should I upgrade to which version of samba I am running a RedHat system 2.6.9-42.0.2ELsmp
