[Samba] samba-2.2.3a with ldap: no logins after a while

[Andreas Hasenack]

I'm still in the process of gathering logs and such. So far, I have tcpdump
captures (yeah, I know 2.2.5 is out, will try it too).

Randomly, it seems, the server will be deaf to logon requests from win98
workstations.

Network traces show that the workstation:
- sends to the broadcast address: NETLOGON LM1.0/LM2.0 LOGON REQUEST
- after 3s, it repeats it twice quickly and then sends the same thing to 
  the samba server (specific IP).
- 3 more seconds and it tries the broadcast address again and then the specific
  IP of the samba server.

After a while, the workstation stops trying and errors.

As I said, I'm still analyzing logs (have over 80Mb to go through!), so far 
I only found the following in the logs of a specific machine (log.netbios-name-of-the-machine):

[2002/04/29 15:45:09, 4] smbd/lanman.c:get_server_info(1179)

(...)

What does this "dom mismatch" mean? Could this be related?
Has anybody experienced this behaviour before?
BTW, the machine is really lightly loaded, it barely touches 0.5 load avg.
