Help with Samba 3.0.20b

[Hiemisch, Joerg]

Hi all,
 
I have a problem with samba 3.0.20b on SUSE-LINUX
 
I try to connect to a server that supports NTLMv2 only. 
I cant join the domain but I can't connect to the server.
 
Debug output of smbclient gives the error below:
 
  NTLMSSP_NEGOTIATE_KEY_EXCH
convert_string_internal: Conversion error: Incomplete multibyte sequence(§EDC4rfv)
NTLMSSP Sign/Seal - Initialising with flags:
Got NTLMSSP neg_flags=0x60080215

I was looking at google and so on, but I couldn't find an answer.
 
Can anyone help me?
 

Joerg
