[Samba] smb "protocol negotiation failed"

[shrek-m at gmx.de]

hi,

since a few hours i get an error

     "protocol negotiation failed"
     "SMB connection failed"

while mounting with

  smbclient //ip-adress/share
  mount -t smbfs -o username=user,password=pwd //ip-adress/share /mnt/smb


the same commands are working since ~1 year via  scripts/console


ping, nmap, telnet <open_ports>, ...
   without problems


137/udp    open        netbios-ns
138/udp    open        netbios-dgm
139/tcp    open        netbios-ssn




server:
   w2k-server sp2

linux-clients
   rhl 7.3
   samba-2.2.3a-6


i will try an update, but i think without luck



google, mailinglists, ...
     nothing found :-(
