Samba problems

[BobC]

Hi,
I have 10.4.7 Server, AFP, Samba, OD. The server is an OD master, bound to AD machine for auth. My Windows users lose access to server in random time, several times a day. Samba log is full of following entries:

The server is WG Master, Domain Master Browser, WINS is enabled. Any idea?

How many Windows connections? I have found this when I have over 100+ connections on one server. Last time I talked to Apple people they were recommending no more then 125 for one server.

Hi,
I have up to 20 connections only.

Your server wouldn’t be accessible to the outside world would it? Meaning it has an outside IP or doing NAT?

I’m having the same problem, yet i only have one SMB user attempting to write files to the server – anyone have any ideas on what to do to fix this?? how do we get apple tech support??

[Anonymous]

Same problem here. We have only a few users too. Ideas?

[Anonymous]

Same here. In my case there’s also this peculiar error (I stopped paying attention to broken pipes):
[2006/10/19 12:19:17, 2] /SourceCache/samba/samba-100.4/samba/source/smbd/trans2.c:call_trans2setfilepathinfo(3691)
file_set_dosmode of somefolder failed (Operation not permitted)

It’s strange that the client would only lose connection to that folder in a larger shared dir. Only a reboot fixes it.
Lately there’ve been cases of trying to connect (unsuccessfully) to a “(99)” share, after the failure. It only happens when users work in a particular directory. Resetting permissions didn’t help.

Same problem here and it is occuring with possibly 5 users connecting at a time. Most of our users use AFP, but the Windows users and a few who connection using the workgroup browser use SMB. This is becoming a huge problem for us. Please post if you have any idea about what this could be. Thanks.

I’ve see those log entries before. Before I went totally AD on the XServe, it was an ODM sharing SAMBA. Folks would tell me they could not browse for it in the Network Neighborhood. They connected using \\server domain name. But it never dropped SMB/CIFS connections.

Does it have a fully qualified Domain name?
It’s Time/Date is in sync with an enterprise- wide NTP service?
Check your kerb principals.
Is it a Domain Member under Server Admin.
