[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 :-(

i think i have to reboot the w2k-server ;-)

the windows-clients had the same problems

i rebooted the w2k-server
-> bluescreen
--> last-known-good

solved all the problems ;-)
