Debian Lenny
Samba 3.2.3
LOOX N560 with Windows Mobile 5


Hello,

 my PDA LOOX N560 could connect via WLAN to SAMBA under Etch. 

Meanwhile I upgraded to Debian Lenny and now may PDA cannot connect anymore to 
the server. Error 1223 or 1222.  
Connecting to XP-Clients via WLAN is okay.

Connecting to Samba Wireshark tells me: 
malformed packet:


No.     Time        Source                Destination           Protocol Info

Session Setup AndX Request, NTLMSSP_NEGOTIATE[Malformed Packet]


The PDA is 10.0.0.245
the server is 10.0.0.247

Any clue, what is going wrong and what to do about it?

Thank you and regards
Bernd Kloss
