[Samba] Problems with Windows 2003 connecting a Samba server

Tue May 29 20:12:25 GMT 2007

Hi list,
   I am encountering a problem in connecting a Windows 2003 to a Samba
3.0.21b server. The Samba server is configured to have a security =
share option, so that no password is needed. I can connect to the
server by typing "net use z: \\192.168.51.1\data", and it is
successful. However, if I try to do "dir z:", no file found! Same
behaviour are found in Windows operation, i.e. type
"\\192.168.51.1\data" under Run box in Start Menu. Strangely, another
server with 3.0.14a does not have such problem, and another Windows XP
does not have such problem too! They can view the files in share
easily.

Here comes the log file:

(Yes, they are in 2 subnets because they are connected by an IPSec
tunnels.. however other client that does not exhibit the problem are
under the same tunnel!)

If a level 10 log is needed, just tell me and I will post it here.

Any help is appeciated. Thanks very much!
