Samba access no longer working in Windows 7

Hi,

I've recently been experiencing an issue connecting to my Samba shares on a Ubuntu 10.4 server box on my network from a Windows 7 client. If I use Ubuntu 10.10 on the same machine, or a Windows XP Virtual Machine running under both Windows and Linux host the share works absolutely fine.

What happens is if I browse to the hostname or the IP address I see a login prompt (there is access control) but my username and password no longer work. Before I didn't need to login as they are the same as my windows credentials.

I'm not sure what information/logs etc would be most relevant so I've posted some information, if any more is required then let me know where to find it and I'm sure I'll be able to get it.

Here is the last few days of the log when I believe it was working, there are no entries since.
Code:

Finally I have tried several of the security policies changes under Windows 7 (unfortunately I can't remember which) and this hasn't helped. The issue first happened just before Christmas so I guess either Windows or the server did an update at that time which has caused this issue.

Hopefully someone has experienced the same issue because I am unsure where to go to find the best support if this is a Windows issue.

If it's windows7 that's not connecting, windows7 may be able to join group.
Also check /etc/host or guest allow(not sure) on server, it may have updated while your machine was not on network.

This may help you

Hi, thanks for your response.

I'm not sure what you mean by 'windows7 may be able to join group'?

I have a public share using samba which does have guest enabled, although I am unable to access this share either it is still prompting for a username.

The text with /etc/host is:
Code:
tom@bahamut:~$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       bahamut.cable.virginmedia.net   bahamut

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
Does that help at all?

I can't see how my config file would be the problem as this has been working perfectly for months, I'm having a look through the options but so far to no avail.

Regards

When it prompts for login credentials on your Win7 box. For the user name are you specifying the group/domain IE: workgroup\username and then the pw?

Hi, thanks for your response.

I just tried it by resolving the workgroup and unfortunately no such luck. It sill can't seem to login.

Windows7 has join group feature under network & sharing center.
You can either create another group or join group.
I don't know if it will join a linux group, but worth a shot.

Unfortunately that didn't see to help either, not sure you can join a Linux group either. Interestingly I fired up the Windows Network Diagnostics and it claims the problem is: 'The remote device or resource won't accept the connection'.

Try a re-install
Short version: Try using the Synaptic Package Manager to "re-install" the samba package. This option will not overwrite your configuration files (although you should back them up in case).

Long version: I have no clue why this worked. I experienced a similar problem. I had 64-bit Windows 7 systems happily accessing Ubuntu 10.04 file shares (as both network shares and mapped drives). Then, at some point that I sadly failed to document (i.e. at some point during a series of Windows and Ubuntu/Linux updates) the file shares stopped working, for no apparent reason. And, more curiously, the failure happened in stages: first the server stopped showing up in the "Network", but could still be browsed if I typed in the server name, and the mapped drives continued to work; second, everything went down (net view resulted in error code 53, network diagnostics resulted in "The remote device or resource won't accept the connection"). Throughout, my settings on both the Win 7 and Ubuntu boxes were unchanged, as were their network settings and availability.
In desperation, I decided to uninstall Samba and re-build the configuration from scratch. As an interim step, I tried the "re-install" option for Samba in the package manager. Magically, I have file access again, though I still can't see the server in the Win 7 "Network" list.
Go figure.

I just gave that a go and no such luck. I tried the reinstall method, no change even with a restart of both machines. I then tried reinstall after removing first and still nothing.

I'm pretty sure whatever has changed is my Windows 7 machine now as the shares work on my house-mate's machine which is also using Windows 7 x64 and the shares are still available under XP and Linux.

Thanks for the suggestion!
