Samba problems with Windows 7

[jordank]

I have been running Ubuntu 9.04 and samba on my server for a while now. It has usually worked ok, but lately it has been acting up. I will be watching a movie on one of my samba shares and the video will stop. Then when I check my computer the share is unavailable for a minute then it comes back.

I have also had problems with the shares becoming disconnected and not being able to access them at all until I reboot. This can be very frustrating. Here is the error I get when that happens.

An error occurred while reconnecting Z:\
Microsoft windows network: the local device is already in use
this connection has not been restored.

I did some searching and found that Windows 7 had some compatability problems with samba. I have noticed that my roommate never has problems connecting using vista and my modded xbox does just fine. Does anyone know how to correct the samba reliability problems with windows 7.

Have you checked your "Enhanced" TCP/IP settings that come with those Windows 7 and Vista boxes. You might want to see if disabling Autotuning might correct your problem. I think its something like:

netsh interface tcp set global autotuninglevel=disabled

or something like that

----
oh and don't forget to reboot, despite what the other folks may say. this setting will not take effect until you do.

[jordank]

thanks for the quick reply. I have run the command successfully and rebooted. I will test it out for a couple hours and let you know if I still have problems.

[jordank]

The problem is still happening. Do you have any other suggestions?

[scathefire]

Have you tried downstepping you authentication mechanisms?

Ya, I tried that last night.

Anything in the samba server logs? You can also try making sure your NetBIOS Helper Service and NetBIOS over TCP is turned on. The NetBIOS over TCP is under the Network Connection setting. I've seen it do weird things on networks when its not enabled.

Just need to try to determine who is killing the connection: the server or the client.

[scathefire]

you might want to also try setting your NTLM SSP to no minimum if you haven't all ready. Should be under local security, where you adjusted you authentication mechanisms. I've read that is suppose to help.

Here is the samba log for my desktop. it was a big file so the times of these entries are from earlier today when I know the problem occurred multiple times.

I will have to take a look at my netbios settings later tonight. I think i have it set to get settings from dhcp. I will try switching that to enabled. I will also lower those security setting more to see if it helps.

Hi,
for me it seems like Win7 tries too reconnect to samba using no or a wrong password ...
You will be able to determinate the error by increasing the log level of samba.

I have read about a similar problem on a german forum ... still with no solution and no logs.
Yust without any error messages from windows.

I've just found following:
Windows 7 and Samba Issue - windows-7

nikonz seemed to found a solution
